You're spose to go to game, load game, select neo geo game from game list, press play, while loading, create new memory card if you don't have one, if you do select memory card, then insert memory card under game......will now work fine, will ask if you wanna save at the end of the game (recommend going 2 rounds in any game and let computer beat you.....after the continue game, should get something like game over....and then it ask to save card, select yes, seems ok, right.....exit emulator, restart the same game, select memory card again under game, select insert memory card, and it should ask you to load save, but the problem is here, doesn't seem to recognize the card, making it unplayable from where you left off.....this memory card feature didn't work in the last two official releases as far as I know....
