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 29 listings we observed for this game in the last 30 days, we filtered out 24 of 29 (~83%) for quality reasons. The remaining 5 are what we'd actually surface.

  • 22 matched a bootleg / out-of-scope keyword
  • 2 shipped from a region we exclude

What the feed excludes

An eBay search for Mega Man & Bass (GBA) 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 108 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 Mega Man & Bass (GBA) because they are: that's the noise.

Mega Man & Bass: collector & reseller spec sheet

  • What it is: Capcom's 2003 US Game Boy Advance release, a port of the Super Famicom game released in Japan as Rockman & Forte. The US cart is the one this page tracks.
  • Product code and saving: check that the label's product code matches the US release. Ask the seller to confirm the cart saves, since "tested" alone doesn't prove it.
  • Print variants: this page doesn't separate print runs. Ask the seller for label photos if a specific print matters to you.
  • Listing traps seen on this title:
    • Japanese Rockman & Forte carts are often titled "Mega Man & Bass" in English. Check the label and the seller's country before paying US-copy prices.
    • Manual, booklet and box-cover listings sell under the full game title, and some are only a few dollars. Read the title for "only" before assuming a cart is included.

Buying Game Boy Advance games: what to check by condition

These checks apply to every Game Boy Advance 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.
