Manual Save Requirement: Users often encounter issues where progress (like unlocked characters) is lost because they expect an auto-save. You must manually create or update the save file within the in-game settings.

Setting the extra flags to 01 does nothing in the retail game—the character models and movesets were scrubbed from the disc. But the save data proves they were planned. Somewhere in Bandai’s archives, there’s a build of Battle Stadium D.O.N. with a full 24-character roster.

The save data structure is identical, but the icon displayed in the PS2 browser menu changed from a generic “DON” logo to a sprite of Goku, Luffy, and Naruto together.
