hi all. so, i have sonic advance for the gba. (ordered it, came in the mail today.) it works fine. tiny chao garden saves, the game saves, runs like a dream. my issue, however, is the connectivity with sonic adventure dx / adventure 2: battle for the gamecube. when i try and transfer my chao to and from, it gives me an error as if i have NO GAME inserted in the GBA. however, when i remove the cartridge, it downloads the temporary tiny chao garden to the GBA and works just fine. i was thinking maybe wiping the save file may help, however the save file is only for the GAME DATA. there is NO WAY to wipe the tiny chao garden save file. i've unscrewed my cart, and i've taken a look inside. is there any advice you have on this issue / anything i can do to the cart physically to permanently wipe ALL data on it? (thinking that may solve the issue.) as usual, thanks in advance, guys.
