Uhm i KNOW i dont have that, because the one 1 card was formated and the other has... lemme think... quake, read 2 rumble 2, and i tried all different combos of my 4 VMUs they all worked
I just did this with puyo puyo fever, i had to install the custom icon in the options menu to get it to work though. just having the save didnt work. I think the only requirement is the special vmu icon.
