Savegame differences across regions? #145

Closed CobaltoSketcherino closed 8 months ago

CobaltoSketcherino commented 8 months ago

The USA versions of Klonoa: Empire of Dreams and Klonoa 2: Dream Champ Tournament aren't saving correctly. The odd part is that the European release of Empire, and the Japanese release of DCT save perfectly fine. Is there an inconsistency with save types across regions? What should I do to help resolve this?

Make sure the ROM hashes match: https://datomatic.no-intro.org/index.php?page=show_record&s=23&n=0112 https://datomatic.no-intro.org/index.php?page=show_record&s=23&n=1886

I did some digging, even double-checking that I had everything sorted out ROM hash wise, turns out my gba_db.bin was the culprit. I think I must've gotten an old version of that somehow. Sorry for the trouble, and I absolutely LOVE the work you're doing!

Oof, i really should add a header with hash to the db format so it can be verified. I already saw issues like that coming.
