The G6's save states are stored in the .is0, .is1 or .is2 file, depending on which slot you saved it to in the in-game menu. If you are using Goomba's save states (if Goomba even has save states), they would be stored in the .0 file.
All of these files are in the GBA folder on the G6.
Alrighty, they must be held within the .0 file - Goomba does have save states. I didn't realize those could be saved into the .0 file.
Thank you very much! I'll go ahead and do a save check right now and see if that's the case and then edit this post with the results.
EDIT
STRANGE OCCURANCE: I SET UP A SAVE VIA STATES, BACKED UP MY ENTIRE CARD ONTO MY COMPUTER, LOADED UP THE GAME AGAIN AND MOVED TO A DIFFERENT AREA, SAVED THE STATE, AND REMOVED THE FLASH CARD. I THEN LOADED THE BACKUP OF MY CARTRIDGE BACK ONTO THE CARD, ERASING THE ENTIRE CARD AS IS AND REPLACING EVERY FILE WITH ITS BACKED UP STATE.
Logically this should have replaced my save with its prior state, however I booted it up and it's STILL THERE. STILL AT THE SPOT THAT SHOULD HAVE BEEN ERASED.
Holy crap. There must be some backup memory somewhere that's unaccessible.
