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 6 listings we observed for this game in the last 30 days, we filtered out 3 of 6 (~50%) for quality reasons. The remaining 3 are what we'd actually surface.
- 2 matched a bootleg / out-of-scope keyword
- 1 shipped from a region we exclude
What the feed excludes
An eBay search for Astro Boy: Omega Factor (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 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 Astro Boy: Omega Factor (GBA) because they are: that's the noise.

Astro Boy: Omega Factor: collector & reseller spec sheet
- Release: Treasure developed it and Sega published the US release for Game Boy Advance in 2004. The Japanese original is titled Astro Boy: Tetsuwan Atom - Atom Heart no Himitsu, so imports show up under a different name.
- Region: this page tracks US copies. Listings that name PAL or Europe, or ship from Japan, are filtered out of the feed.
- Print variants: no reprint tiers we can state with confidence. Confirm the label and product code match the US release in a clear seller photo.
- Listing traps seen while tuning: manual-only and poster-insert listings carry the full game title, as do display dioramas, so read the item description before assuming a title means a cartridge. Graded sealed copies also appear at much higher asking prices than raw sealed ones, so compare like for like.
- Save check: progress is stored on the cartridge, and 20+ year-old save memory can fail. "Tested, saves" in the title is worth more than a bare "authentic".
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.
