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 203 listings we observed for this game in the last 30 days, we filtered out 126 of 203 (~62%) for quality reasons. The remaining 77 are what we'd actually surface.
- 105 matched a bootleg / out-of-scope keyword
- 11 seller had too few feedback ratings
- 7 caught by a junk-listing guard
- 2 shipped from a region we exclude
- 1 seller positive-feedback percentage too low
What the feed excludes
An eBay search for Sonic & Knuckles (Genesis) 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 116 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 Sonic & Knuckles (Genesis) because they are: that's the noise.

Sonic & Knuckles: collector & reseller spec sheet
Sega released Sonic & Knuckles for the Genesis in North America in October 1994. It is a lock-on cartridge: the top has a slot for a second cart, which is why sellers write "Lock-On Technology" in titles.
- Save mechanism. The cart has no save of its own. Locked on to Sonic the Hedgehog 3, it lets that game's saves work. Don't pay extra for a "saves" claim on the Sonic & Knuckles cart alone.
- Top flap and cover. The top slot has a flap, and titles often say "flap intact" or "no flap". Treat a missing flap as a condition flaw and price it below a complete cart.
- Print variants. A Not for Resale copy appears alongside standard retail ones. Check the label against a known authentic photo before paying a premium for it.
- Wrong purchase. Sonic 3 & Knuckles listings, pairs with Sonic the Hedgehog 2 or Sonic 3, and the Sonic & Knuckles Collection PC disc all carry the same words. The feed excludes them, along with Japanese and PAL Mega Drive copies.
- Sealed and graded. Sealed asks run far above CIB, and graded slabs ask the most. Check the seller's feedback before sending money for an unopened copy.
Buying Sega Genesis games: what to check by condition
These checks apply to every Sega Genesis 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 plastic case and cover art 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.
