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 94 listings we observed for this game in the last 30 days, we filtered out 80 of 94 (~85%) for quality reasons. The remaining 14 are what we'd actually surface.
- 36 priced below our floor (too good to be true)
- 22 matched a bootleg / out-of-scope keyword
- 16 caught by a junk-listing guard
- 6 shipped from a region we exclude
What the feed excludes
An eBay search for Legend of the River King (Game Boy Color) 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 98 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 Legend of the River King (Game Boy Color) because they are: that's the noise.

River King: collector & reseller spec sheet
- Publisher & save: the US Game Boy Color release was published by Natsume (1999). It is a fishing RPG that keeps your progress on the cartridge, so it relies on the original save battery. Those flat coin cells are now 20+ years old: budget for a battery swap whatever the seller claims, and prefer listings that say the save was tested.
- Product code: check that the code on the label matches the US release before paying a collector price. If the seller doesn't show the label, ask for a photo.
- Print variants: we can't name a verified variant that moves the price. Sealed and graded copies carry a large premium over loose carts, so judge those by the grading label and the seller's photos.
- Sequel trap: Legend of the River King 2 is a separate Game Boy Color game with near-identical titles and box styling. The feed rejects titles that name the sequel, but check the label on any photo-only listing before you pay.
- Searching yourself: sellers write "River King", "Legend of the River King" and "GBC" interchangeably, so search on "river king" and read the full title.
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.
