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 171 listings we observed for this game in the last 30 days, we filtered out 104 of 171 (~61%) for quality reasons. The remaining 67 are what we'd actually surface.
- 65 matched a bootleg / out-of-scope keyword
- 22 shipped from a region we exclude
- 9 seller had too few feedback ratings
- 4 wrong condition (e.g. parts-only)
- 1 priced below our floor (too good to be true)
- 1 priced above the curated ceiling
- 1 seller positive-feedback percentage too low
- 1 caught by a junk-listing guard
What the feed excludes
An eBay search for Dragon Quest IX (DS) 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 102 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 Dragon Quest IX (DS) because they are: that's the noise.

Dragon Quest IX: collector & reseller spec sheet
- Release & carrier: Dragon Quest IX: Sentinels of the Starry Skies is the Nintendo DS entry from Level-5, published by Square Enix. The US cart's label carries a product code ending in
-USA; check it matches the North American release. Japanese and European copies share the artwork style but are different regional releases. - Saves: progress is stored on the cartridge, so a tested working cart matters more than the box.
- Print variants: a later budget reprint may exist alongside the original retail run. Confirm which one you are buying from the listing photos; value impact varies and the profile does not separate them.
- Listing traps seen while tuning: Japanese copies, strategy guides and guidebooks, and promo or display inserts all carry the game's name. The feed rejects most of them, but read the title closely on anything priced far from the rest. Not to be confused with Dragon Quest VIII, which is a PS2 game.
Buying Nintendo DS games: what to check by condition
These checks apply to every Nintendo DS 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.
