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 47 listings we observed for this game in the last 30 days, we filtered out 31 of 47 (~66%) for quality reasons. The remaining 16 are what we'd actually surface.
- 28 matched a bootleg / out-of-scope keyword
- 2 shipped from a region we exclude
- 1 seller had too few feedback ratings
What the feed excludes
An eBay search for WarioWare, Inc.: Mega Microgames (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 105 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 WarioWare, Inc.: Mega Microgames (GBA) because they are: that's the noise.

WarioWare: collector & reseller spec sheet
- Release & region. The US release is the 2003 Game Boy Advance original. Sellers often spell the title "Mega Microgame$!" with a dollar sign, or "Wario Ware" as two words. The feed matches both spellings. Japanese copies ship under the "Made in Wario" name and are filtered out, so this page tracks US copies only.
- Product code. Check that the label's product code matches the US release rather than a Japanese or European one. Compare against a photo from a trusted listing.
- Save check. Ask the seller whether saving was tested, since "tested" alone may mean it only boots.
- Listing traps. Sellers often bundle it with another Wario-franchise game or a sports title in a single listing, and the feed drops those. Manual-only and empty-box listings carry the full game name but contain no cartridge, so the feed drops them too. Not-for-resale copies are a separate collectible and are also filtered out. Graded sealed copies list at far higher asking prices than anything else, so check the chip before comparing.
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.
