Nintendo DS Condition Notes

DS cartridges are small and easy to separate from their case or manual, so completeness — not physical damage — is the more common issue on this platform. Older cartridges with an internal save battery can fail the same way GBA's do.

How we get to your offer

We pull the live market comp for Petz: Dolphinz Encounter on Nintendo DS, then apply the same locked rates we use on every trade-in: 65% of comp in cash, or 85% in store credit. No lowball guesswork, no per-item haggling. The comp is the only input, and the math is the same for a common nintendo ds cart and a grail.
