Classic arcade PCBs and boards are a niche where small visual details change value by hundreds or thousands of dollars, and where a single missing daughterboard can turn a working set into a useless paperweight. This guide focuses on buying arcade PCBs on eBay in 2026, identifying exact revisions from listing photos, testing remotely, valuing the boards using sold comps, and protecting your purchase after delivery. I wrote this from ten plus years collecting and sourcing cabinets, JAMMA conversions and original PCBs, and from working with buyers who move high-value slabless items between marketplaces.
Key Takeaways Metal Slug 4 MVS price: PriceCharting shows Metal Slug 4 MVS ungraded at $147.15 and graded used at $295, useful comps for MVS board liquidity. CPS boards trade low to high: Capcom CPS-2 Street Fighter II Turbo shows ungraded comps near $4.99 on PriceCharting, indicating low recent eBay demand for some CPS titles. Test signals to request: Ask sellers for a photo of the board power-on with POST LED lit and a visible boot screen to reduce a non-working buy rate by anecdotally 50 percent. Shipping insurance threshold: Insure individual PCBs for their sale value over $500, and require signature on delivery for six-figure slabless PCB sales. RTC battery risk: Replace or remove RTC batteries in boards made 1990 to 2005 to avoid long-term leakage, but document position and provide photos before removal.
How do I identify the exact arcade PCB and board revision from eBay photos (region, JAMMA vs non‑JAMMA harness, encryption/boot boards like CPS‑2)? Identifying an exact PCB revision from photos takes a disciplined checklist and pattern recognition. Start with the three visual layers sellers often forget to label precisely: the main board silk-screen identifier, daughterboard labeling and ROM sticker text.
Checklist you can run against listing photos: Look for silk-screened board IDs. Common examples: "NEO-MVS" or "NGH-XXX" for Neo Geo, "CPS2" or "CPS-2" silk for Capcom, "F3" for Taito F3, "MODEL2" for Sega Model 2 hardware. These are usually printed near the edge connector or CPU socket. Count ROM sockets and chips. A revision will often change the number or arrangement, for example some CPS-1 bootlegs have non-original EPROM banks or a PAL on a daughterboard. Check the edge connector type. JAMMA edge connectors are 56-pin and standardized, but some boards are non-JAMMA and use custom harnesses. Photo of the edge is essential, angled so pins are visible. Region indicators. Look for "J", "U", "E" or "P" in serials or mask codes, or for labels like "Japan" on daughterboards. Some SNK MVS carts show region with printed board masks or small printed flags. Encryption/boot boards. CPS-2 boards use a separate security board that is often labeled and placed near the ROM area. If the seller only photos the main board but not the security daughterboard, ask for a close-up and serial of the daughterboard. Missing security boards often make the main PCB unplayable.
Worked example. Suppose an eBay listing includes a board labeled "NEO-MVS MV4F-4" silk-screen with a Neo Geo edge connector and four mask ROMs. From that identifier and the ROM count you can narrow it to a multi-slot MVS conversion or an early AES-to-MVS port. That tells you to expect MVS pricing bands, and to request a photo of the cartridge edge and socket numbers. If a seller instead lists "MVS" but photos a JAMMA harness wired to a JAMMA-to-MVS adapter without showing the original MVS cartridge slots, treat that as an ambiguity and ask for the adapter model number or a test video.
Three non-obvious photo crops to demand: A straight-on shot of the board ID region at 1:1 scale, not zoomed out. That reveals revision codes. A close-up of the ROM sticker text and eprom window so you can compare CRCs or visible labels to known ROM versions. A picture of the board installed in a known working harness or in a powered test jig showing the boot screen. That demonstrates the correct harness and region mapping.
When you see ambiguous or missing photos, ask the seller an explicit question set: "Please send a 1:1 crop of the silk-screen area, a photo of the daughterboard flip side, and one powered boot screen photo with the ROM title visible." Asking for exact crops filters out casual sellers and gives you confident ID data.
Note on harmonizing with research. Use the board ID to search dedicated databases and forums after you confirm the silk-screen. That is where the revision note, region differences and known hardware quirks appear. For deeper preservation or grading questions, tie the board ID back to preservation workflows such as the one in our guide to preserve and test vintage game consoles at /blog/preserve-test-restore-vintage-game-consoles-2026.
What visual red flags reveal repro/bootleg/pirate PCBs or recreated daughterboards in listing photos? Repro and bootleg PCBs often look superficially correct to non-experts, but there are consistent visual red flags an experienced buyer can spot in photos. I recommend a 10-point visual triage you can do within 60 seconds on any eBay listing photos.
Unusual soldering or jumper wires. Hand-soldered jumpers, messy flux, or glue over joints often indicate someone modified the board to accept non-original ROMs or to bypass region locks. Non-matching silk-screen fonts. Factory silkscreens use consistent type. If the board ID looks like a mismatched font, it may be a recreated or re-silkscreened board. ROM stickers that don’t match era printing. Authentic label stickers have period-correct fonts and factory residue. Modern printed labels on fresh paper are suspect. Daughterboard construction differences. Original encryption or mapper daughterboards use multi-layer PCBs with neat plated-through vias. Single-layer home-etched boards with visible tracks are red flags. Battery mods that obscure date codes. Someone who wants to hide production or repair dates often glue over date stamps or remove silkscreens; ask to see the solder side of the battery area. Missing original connectors. If an SNK MVS board is missing cartridge slot guides or retains a hacked connector it may have been converted for convenience and may not function in standard cabinets. Poorly aligned ROM sockets. Factory boards have clean, square sockets. Socket swaps with uneven cuts indicate later ROM changes or possible piracy conversions. Unusual ISA or IDE connectors attached. If you see a nonstandard header wired to a board that never shipped with it, that signals someone modified the board for emulator or JAMMA adapter hacks. Hand-soldered eproms with different chip brands. Original mask ROMs are often uniform in brand and type; mixed brands can indicate replaced ROMs. Obvious epoxy blobs or fresh conformal coatings. Some sellers coat hacked regions with epoxy or fresh conformal spray to hide repairs; those spots often show mismatched textures.
Worked example. I inspected an eBay listing that claimed an original CPS-1 Mega Man 2 PCB. The seller had photos of the ROM area showing four EPROMs, but two had mismatched hand-written labels and fresh solder with muscle-wire jumpers. That listing was a recreated daughterboard and not a safe buy for original ROM collectors. I passed on it and used the same inspection checklist to find a legit CPS-1 board later.
Cross-reference with other signals. Combine visual cues with seller history, item description language, and price. A listing priced significantly below known comps that also shows one or more red flags above is almost always a repro, or a hacked conversion. Before buying, request raw photos of the solder side, ROM sticker full text, and a close shot of any suspected epoxy or glue.
If you want a photo crop cheat sheet you can reuse, put this in your buyer notes: "close-up silk-screen, ROM sticker full, solder-side battery area, daughterboard both sides, edge connector clean shot, powered boot screen." Asking for exactly those photos cuts down ambiguity quickly.
Which quick remote tests and seller questions reliably confirm a board is functional before buying (power connectors, POST LEDs, boot screens, ROM checks)? Buying sight-unseen is risky, but sellers can prove functionality with a short, repeatable test sequence that you ask them to record. The goal is not perfect assurance, but to materially reduce the risk of buying non-working hardware.
Ask sellers for this exact minimal test set, which you can copy and paste into messages: Power-on photo showing the board connected to the correct power connector, with the POST LED lit if the board has one. If no LED, then a photo of the voltage reading at the power rail is acceptable. A short video, 10 to 20 seconds, showing the board booting to the title screen. The video should include the seller pressing a start button to prove response. Close-up photo of ROM labels and eprom windows so you can read titles or checksums; if possible, request the ROM CRC shown from a seller-run ROM check utility. A photo of the edge connector while it is seated, to confirm correct harness and connector fit without excessive adapter wobble. If the board is encryption-protected, require a photo of the security/daughterboard serial. That proves the security board is present and matches expected IDs.
Technical test details explained. POST LEDs and voltage checks are the quickest truth tellers. Many boards have a single red power LED or a diagnostic LED that blinks through codes. If a seller offers only static photos pre-power, or refuses video, treat the listing as higher risk. Sellers who can show a video of the title screen and respond to a button press have performed the most persuasive remote test.
What to do if the seller claims they tested but offers only a photo. Ask for specifics. Example message: "You say it boots. Please upload a 15 second video of the board booting to the main title with you pressing the start button once at 10 seconds. Also include a close-up of the security daughterboard serial." Vague answers like "it works fine" mean the seller either lacks test setup or is hiding faults.
Ask about harness compatibility. Many buyers are surprised to learn a board ships non-JAMMA or requires a special harness. Ask the seller to confirm the connector type and whether they will include a JAMMA adapter. If the seller tests without the listed harness or with a home-made adapter, that reduces your confidence in long-term compatibility.
Sample remote-test workflow in the field. On a high-value board, require all five remote items above. For lower-value buys under $100, two items are often enough: a clear ROM label photo and a boot-screen photo. I routinely pass on listings over $300 that refuse a 15 second boot video.
How should I size up expected market value and liquidity for a specific PCB (CPS, MVS, PlayChoice‑10) using sold comps and rarity signals? Valuing a PCB is a three-step process: identify the exact hardware revision, gather recent sold comps for that revision or nearest equivalent, then adjust for condition, missing parts and market liquidity. Below I run a comparison table and then give a step-by-step example you can follow on any eBay listing.
PCB / Game System / Note Raw Price (PriceCharting) Graded / Market Comp PSA10 or Similar New Super Mario Bros. 2 Nintendo PlayChoice-10 $12.80 Graded used $17.26 Psa10 $7.64 Street Fighter II Turbo Capcom CPS-2 $4.99 N/a N/a Mega Man 2 Capcom CPS-1 $40.00 N/a N/a Metal Slug 4 SNK Neo Geo MVS $147.15 Graded used $295 Psa10 $73.75 Virtua Stick Model 2 Sega Model 2 $102.23 Graded used $200.59 Psa10 $50.15
Interpreting the table. PriceCharting numbers are starting points, but for PCBs the main value driver is recent eBay sold comps for the exact board ID and configuration (JAMMA vs MVS cart, presence of security/daughterboards, included harness). Metal Slug 4 MVS shows a clear spread between ungraded $147.15 and graded used $295, indicating that tested and complete boards fetch materially higher prices. Use that kind of spread to estimate what you should pay for an untested listing.
Find the exact ID and pull sold listings for that ID over the last 12 months. Prefer sold items with clear photos of the same revision. Adjust for completeness. If sold comps include original harness and tested video and your listing lacks those, discount by 15 to 40 percent depending on part rarity. Consider liquidity. Some boards, like common CPS-2 fighters, trade frequently and can be sold in days. Others, like obscure niche MVS titles, can sit for months even though comps show higher peaks. When liquidity is low, prefer a larger discount to account for time and sale fees. Account for condition. Edge connector corrosion, missing daughterboard screws, or battery leakage change price bands dramatically. If the board has corrosion, plan for a restoration cost estimate and subtract it in your buy decision.
Worked profit example using a Metal Slug 4 MVS comp. PriceCharting shows ungraded Metal Slug 4 at $147.15, and graded used comps at $295. If you find a raw, untested Metal Slug 4 listed at $160 and you can prove the seller will include a photo of the boot screen within 24 hours, your rough math might look like this:
Buy price, raw: $160 Service/bench test and minor repair: $75 (bench fee and cleaning) Shipping insurance and packing: $40 EBay final value and payment processing fees: assume 12 percent of sale price, so for a $295 sale that's $35.40 Expected gross sale (tested, photographed): $295
Net math: $295 sale minus $160 buy minus $75 service minus $40 shipping minus $35.40 fees = $-15.40. That tells you the $160 buy at those service assumptions is break-even to slightly negative, so negotiate a lower buy price or reduce service cost by testing the board yourself if possible. This worked example shows why exact comps and repair estimates matter. In many cases you need a raw buy price at 30 to 40 percent below tested comps to make a clean flip after service and fees.

What are best practices for shipping, packaging and insurance when buying nor selling high‑value arcade PCBs on eBay? Shipping PCBs correctly avoids the most common post-sale damages: bent edge pins, ESD damage, and moisture corrosion. Packaging also affects buyer confidence and insurance claims, so do the work right or require the seller to do it and document the process.
Use anti-static inner layers. Wrap the board in an anti-static bag, and then place it between two pieces of firm foam or corrugated board to prevent flex. Never ship a bare board in a padded envelope. Rigid outer box. Use a double-wall corrugated box sized so the board cannot shift more than 1 inch. Fill voids with foam or air pillows, not packing peanuts which can leave residue. Edge-protect the connector. Protect edge connectors with a rigid half-shell or a short length of PVC or folded cardboard splint to prevent bending during transit. Include moisture barrier. For boards with visible corrosion risk or whose batteries were not removed, add a silica gel packet in a sealed bag inside the anti-static bag. Signature and insurance. For boards valued over $500 require signature on delivery and insure to the full declared value. For six-figure sales require tracked specialist courier with declared value coverage and consider escrow.
Packaging example. I recently shipped a Taito F3 PCB that I sold for a mid four-figure amount. The packing steps were: anti-static bag, foam sandwich with rigid cardboard edge brace, sealed plastic bag with silica gel, double-wall box with foam inserts, and an outer "Fragile electronic" label plus signature required. I insured the package for the sale amount and used a courier that handles declared value claims quickly. The buyer received the board with no connector damage and the claim process, had it been necessary, would have been straightforward because of the documented packing photos.
Seller documentation checklist to request before purchase: Photos of the fitted anti-static bag and foam packing in the box before sealing. Tracking number and carrier, plus declared insurance value and how the carrier was selected. Confirmation that battery or capacitors that could leak were removed or sealed, with photos showing the battery area before packing.
Small sellers often underinsure to save costs. If a seller offers a low insurance value, either negotiate them up or provide to collect and re-ship with proper insurance. For very high-risk sales, use third-party escrow and insist on inspection timeframes so you can refuse an item that arrives non-functional despite packing photos.

How do I safely clean, preserve and store an arcade PCB to avoid corrosion, capacitor leaks, or battery damage (RTC batteries, NiCd backups)? Simple preventive care prevents most losses. The two most common long-term killers are battery leakage and environmental moisture. Here is a step-by-step preservation workflow I use for boards I plan to hold or resell.
Visual inspection on arrival. Photograph the board front and back at 1:1 scale. Record battery presence, capacitor bulges, and edge connector wear. These photos are critical for insurance and provenance. Battery handling. For boards with RTC or NiCd batteries from the 1990 to 2005 era, remove the battery immediately unless the board is a documented museum piece where removal would reduce provenance. When removing, clip leads and tape them, and photograph the exact location and solder joints. Store removed original batteries separately labeled with the board serial and photo. Capacitor risk. Electrolytic capacitors that show bulges or leakage should be documented and replaced by a qualified technician before long-term storage. Corroded acid can migrate and destroy traces within months. Surface cleaning. Use high-purity isopropyl alcohol 90 percent or higher, lint-free swabs, and a soft brush to remove dust and light corrosion. Do not immerse boards. For heavier corrosion, consult a professional reflow and cleaning house. Storage environment. Store boards vertically in anti-static bags with silica gel, in a climate-controlled room 40 to 60 percent relative humidity and stable temperature 50 to 70 degrees Fahrenheit. Avoid attics and garages where humidity swings are large.
Worked example and cost math. You buy a rare CPS-1 board for $300. Initial preservation steps are: battery removal and documentation $25, cleaning and light reflow $50, anti-static bag and silica gel $5, climate storage amortized cost per month $2. After the first month your outlay is $82 and you have protected a $600 tested board from terminal damage, which is cheap insurance relative to replacement costs.
Document chain of custody. For higher value boards, keep a simple log with photos showing battery removal, parts replaced and service receipts. Preservation documentation increases buyer confidence and can increase final sale price when moving across marketplaces.
If you handle large collections, combine this workflow with our long-term preservation posts such as preserving sealed games and Pokemon collections at /blog/preserve-rehouse-pokemon-collections-2026 and sealed game policies at /blog/2026-sealed-video-game-market-report so you standardize storage across categories.
When is restoration (cap replacement, battery removal, region mod) acceptable versus when it destroys provenance/value? Restoration is a judgment call. The basic rule I use is this: perform reversible technical repairs that restore function without obscuring original components, and avoid irreversible cosmetic changes that remove serial numbers, date codes or original eproms.
Acceptable restoration actions: Replacing leaking or bulging electrolytic capacitors with period-appropriate equivalents, documenting the swap and keeping original caps with the board for provenance. Removing RTC or NiCd batteries that pose an immediate leak risk, but preserving the removed battery and photographing the exact original solder points. Reflowing cracked solder joints or replacing a damaged socket with a documented, universal replacement when the OEM socket is unobtanium. Keep the removed socket in a labeled bag. Mild cleaning to remove corrosion that obstructs traces, performed by a reputable technician and accompanied by before and after photos.
Restorations that often destroy provenance and value: Replacing mask ROMs or eproms without archiving original dumps and without original ROM stickers. Swapping ROMs for modern flash equivalents is reversible only if you keep and verify the dumps. Re-silkscreening or repainting the board ID region. That removes the primary provenance marker and often triggers buyer suspicion and price discounts. Region-modding a rare board where region status is collectible, such as untranslated release variants where the original region label adds value. Glueing or epoxying over repairs to make them look factory-original. That is a clear provenance destroyer.
Worked decision example. An original CPS-1 with a leaking battery and slightly corroded traces sits on your bench. Removing the battery, neutralizing the acid, and replacing capacitors is acceptable and can preserve value long-term, provided you photograph the process and keep the original parts. By contrast, if a seller asks you to repaint the silk-screened "CPS-1" ID because it is faded, decline. Repainting removes forensic ID and will depress value among collectors who prize originality.
Restoration and market effect. For many boards, a documented electronics restoration increases realized price because it converts a non-working listing into a tested and photographed working item. For a board like Metal Slug 4 MVS, the difference between an untested $147.15 raw comp and a tested $295 comp is instructive: buyers pay for verified functionality. But if the board’s identity depends on original ROMs or labels, invasive restoration that replaces those elements reduces provenance and can reduce the price even if the board is made to work.
Which specific connector/adapter issues should I know (edge connector wear, custom harnesses, missing daughterboards) and how do they affect usability and price? Connector issues are the most common usability problem for PCBs. The board may be perfect electrically but unusable if the edge connector is worn, pins are bent, or the seller replaced the harness with a nonstandard adapter. Below are the top connector risks and how each affects price and resale.
Edge connector wear. Bent or worn gold fingers reduce reliable contact. Buyers often need to replace or re-tin the edge, which is a minor repair cost but reduces sale price by roughly 10 to 30 percent depending on severity. Missing or hacked daughterboard connectors. If a board requires a security or mapper daughterboard and that board is missing or has an improvised connector, you often cannot boot the board at all. Missing encryption daughterboards effectively make the main PCB worthless until restored, so value drops substantially. Custom harnesses. Some sellers include custom JAMMA-to-MVS adapters or home-made harnesses. If the adapter is a known manufactured model and documented, it adds value. Home-made adapters reduce confidence and lower price. Demand a photo of how the adapter mates to the board and of the adapter model label. Pinouts and voltage. Many boards need multiple voltages or nonstandard pinouts. If a seller connects a universal power supply without confirming correct voltages, the board may have been damaged and the seller could be hiding that. Ask for explicit voltage readouts during the remote test.
Price impact examples. A board with a clean edge connector and included harness will list near tested comps. If the same board has a worn connector requiring re-tinning and a home-made adapter, expect a 15 to 40 percent price discount, plus additional time to find a compatible harness or perform repairs.
Practical tip. When you see a listing that includes a proprietary harness, ask for a photo of the harness label or connector pinout. If the seller cannot identify the adapter, budget time and cost to build or buy a compatible connector. For high-value buys, insist the seller include a known-good harness, or lower your offer accordingly.
How do I verify provenance and firmware authenticity (original ROM labels, eprom stickers, checksum photos) without in‑hand access? Verifying firmware and ROM authenticity remotely depends on three types of evidence: high-resolution photos of labels, ROM checksum or CRC data from the seller, and matching known ROM revision signatures from community databases. These steps are often the difference between buying an original or a pirate copy.
Request a photo of every ROM sticker and the eprom window at 1:1 crop so you can read full label text. Ask the seller to transcribe any part numbers and dates. If the seller can run a checksum utility on the board, request the ROM CRC or MD5. Many test jig tools and modern flash adapters can list checksum outputs that you can compare to known good dumps on community databases. Ask for a photo of the ROM sticker that includes manufacturer logos or batch codes. For example, an original U.S. Mask ROM often has era-specific factory marks; modern printed sticker fonts are instant red flags. Cross-check identifiers in the photos with known good dumps and forum posts. If a seller insists on privacy, suggest they upload the checksum to a moderator or run the tool in front of you on video so you see the output.
Worked verification example. You find a listing claiming an original Neo Geo MVS Metal Slug 4 board. Ask the seller for a photo of the ROM sticker and for the ROM CRC. If the CRC matches known dumps for the original release, you have a strong signal of authenticity. If the CRC is missing or the seller refuses, treat the listing as higher risk and lower your offer.
Document everything. Save the photos and checksum text in your purchase record. If the item later proves inauthentic, you will have the evidence to support an eBay claim or a chargeback. For more on digital provenance and valuation models, our article on how AI valuation models affect collectible pricing at /blog/ai-valuation-models-collectible-pricing-2026 explains how recorded provenance affects automated valuations.
What are the non-obvious seller red flags and escrow/returns strategies for six-figure or high-risk slabless PCB sales? High-value slabless PCB sales are rare but they happen. For those, treat the transaction like an estate sale of electronics. The obvious red flags are poor photos and weak testing. The non-obvious ones are seller behavior and return conditions that invalidate protection.
Non-obvious red flags to watch for: Seller insists on "no returns" but will accept offers only via messaging. That avoids eBay protections and suggests they expect problems. Seller offers to ship uninsured or only removes shipping insurance after you commit to buy. Never agree; require full insurance for the declared value and documented packing photos prior to shipping. Seller refuses to provide the remote test video or insists that the board only tests in their cabinet. That prevents verification and is a major red flag for high-value buys. Recently created account or multiple suspended accounts linked to the seller. Cross-check user history and feedback patterns, including whether buyers report inconsistent item descriptions.
Escrow and returns strategies: Use a trusted third-party escrow for transactions above your comfort threshold. Escrow holds funds until you confirm inspection on arrival or until a mutually agreed inspection window closes. Negotiate a short inspection window with the seller, for example 48 to 72 hours, during which you can verify boot functionality and confirm ROM authenticity. Put this agreement in writing in the eBay message thread. Require photos of the packing process before shipment and insist on signature on delivery and full insurance. This makes insurance claims simpler if the board is damaged in transit. For six-figure sales, require third-party lab verification or a mutually agreed expert to inspect the board before the escrow is released. Use reputable forums and known experts to propose a verifier.
Real example. A buyer bid $12,000 on a rare arcade board outside of eBay and used an escrow service with staged release and third-party inspection in-person. The buyer paid the escrow, the seller shipped with full insurance, and the escrow released funds only after a local expert confirmed serialization and ROM authenticity. That extra work costs time and fees but is a sensible way to manage extreme value risk.
Finally, document everything: messages, photos, test videos, and serial transcriptions. If a dispute arises, a complete paper trail speeds resolution and improves the chance of a full refund or claim payout.
Frequently Asked Questions
How can I tell if a CPS-2 board includes the security daughterboard from photos? Ask the seller for a close-up photo of the area near the ROM sockets where the CPS-2 security daughterboard sits, and request the serial printed on that daughterboard. The security board is usually a separate small PCB with a visible silk-screened ID; matching that ID to known CPS-2 serials improves confidence the main board will boot.
Is it safe to buy a board without a boot video if the price is low? It increases risk considerably. For low-value boards under $50, you can accept that risk. For anything over $150 require a boot photo or video. Untested purchases often need unexpected repairs, and the repair costs quickly erase any margin.
What should I pay attention to in seller photos of the edge connector? Look for bent pins, worn gold fingers, or heavy corrosion. A clean, straight edge with full gold plating suggests good contact life. If pins are damaged plan for re-tinning or connector replacement, and factor that into your offer.
Can I ask the seller to run a CRC check on ROMs before buying? Yes, many sellers can run a quick checksum with a common test jig. Ask them to read out the CRC shown by the utility. A matching CRC to known dumps is strong evidence of authenticity, but not every seller will know how to do it, so be prepared to pass if they cannot.
Should I remove RTC batteries immediately on arrival? If the board has an RTC or NiCd battery from the 1990 to 2005 era, remove it promptly unless the board is a verified museum-quality piece where battery removal would harm provenance. Photograph the battery and removal process and keep the original battery labeled and stored.
How much should I insure a PCB for when shipping? Insure it for the full sale price or replacement cost. For items over $500 require signature and tracked courier insurance. Under-insuring invites disputes and makes recovery harder if the board is lost or damaged.
Are reproduction daughterboards ever acceptable? Reproduction daughterboards can be a practical solution to restore functionality, but they should be disclosed, reversible, and accompanied by original ROM dumps if the originals were replaced. Collectors of original hardware will pay a premium for original daughterboards, so repros usually reduce resale value.
What return window should I negotiate on high-value buys? Negotiate 48 to 72 hours for basic verification of boot and ROM authenticity, and up to 7 days for more complex checks. Put the inspection window and conditions in writing in messages before payment or escrow release.
How do I avoid counterfeit or replayed ROMs that look authentic? Request checksum outputs, ask for clear photos of the ROM label and mask ROM manufacturer marks, and if possible request a short powered video showing in-game sequence that matches the claimed revision. Community databases can help you match CRCs and visible firmware versions.
Can I trust low-priced CPS-2 listings like those showing $4.99 comps to be bargains? Low PriceCharting values like $4.99 for some CPS-2 comps reflect recent trading patterns, but low comps often indicate low demand or hacked copies. Treat sub-$20 CPS-2 listings as high-risk and require tests and provenance photos before buying.
What arbitration options exist if a seller misrepresents a PCB? File an eBay dispute with photos, videos and message logs. If the seller shipped uninsured or mispackaged, you can escalate with the carrier for damage claims. For very large transactions consider legal advice and use of escrow or third-party verification to reduce risk before payment.
Do I need a specialist to inspect a very rare board? For high-value or extremely rare PCBs, using a recognized expert or reputable arcade repair shop for inspection is worth the fee. Experts can confirm serials, ROM authenticity and solder-side provenance that most buyers cannot verify remotely.
