How we filter
Every feed has its own filter, tuned by hand for this one game. Before any change goes live, those filters are tested against thousands of real eBay listing titles. Every night, each feed is checked against every other deal page in its category, so a listing for a different game that slips in gets flagged and fixed instead of quietly shown.
Of the 18 listings we observed for this game in the last 30 days, we filtered out 3 of 18 (~17%) for quality reasons. The remaining 15 are what we'd actually surface.
- 2 matched a bootleg / out-of-scope keyword
- 1 seller positive-feedback percentage too low
What the feed excludes
An eBay search for Operation C (Game Boy) returns far more than the game itself: controllers, T-shirts, strategy guides, imports and repro carts all mention it in their titles. These are the 96 terms we filter out to keep this feed to the real thing. A listing whose title contains any of them never reaches the feed, the price table or an alert. Many look unrelated to Operation C (Game Boy) because they are: that's the noise.

Operation C: collector & reseller spec sheet
- Product code: US carts carry a
DMG-CN-USAlabel code in seller listings. Check the code on the label matches the US release before paying a premium. Japanese copies are a different release under the Contra name, and this feed filters them out. - Two names, one game. Sellers list it as "Operation C", "Contra Operation C" or "Contra: Operation C". The feed matches the "Operation C" wording, so every spelling lands in the same place. It is a separate game from the NES Contra.
- Publisher label. The US release came out under Konami's Ultra Games label, so listings say "Ultra", "Konami" or both. All three mean the same cart.
- Print variants: no variant premium is documented here. If a seller advertises a specific print or revision, ask for a label photo and compare it to a known authentic one.
- Listing traps: manual-only and VIDPro-card listings carry the game's name at a collector price and are not the game. The feed also screens out manuals, booklets and multi-game lots, but check the title for "manual only" or "card" before buying. "Graded" and sealed copies sit at a very different price level from loose carts, so read the price table by condition before judging a deal.
Buying Game Boy games: what to check by condition
These checks apply to every Game Boy cartridge. The item notes above cover what is specific to this game.
Loose
- Compare the label, shell color and front/back markings against a photo of a known-authentic cart. Repro labels are often glossier, blurrier or slightly off-color.
- Ask for a photo of the board or the back of the cart. An opened shell is not automatically bad (battery swaps are normal), but it should be disclosed.
- If the game saves to a battery, ask whether the save holds. Old save batteries fail with age regardless of what the listing says, so budget for a replacement.
CIB (complete in box)
- Confirm the box, manual and inner tray or insert are all shown in the photos, not just listed in the title.
- Check that the box and manual are the same region and print as the cart. Mixed-and-matched "complete" copies are common.
- Box wear (crushing, tears, sticker residue) moves price far more than the cart does. Judge it from photos, not from the word "mint".
Sealed & graded
- For a graded copy, look the certification number up on the grading company's own site and confirm the photos match the slab you are buying.
- For an ungraded sealed copy, compare the wrap and seal pattern against a known factory-sealed example. Resealing is common, and a reseal on a loose game is worth a loose price.
- Ask for photos of every side, the seams and any price stickers. Refusing extra photos on a sealed listing is a red flag on its own.
