You cannot put gba games onto the card.
whiles on the subject of this app does any one know where the hell the saves are saved to as this is the only reason iam not using it i know that it creates a config file that has fat:\name of rom in it though is this on the ram of the slot2 card i have Ez-Flash 3 in 1 and if i load up the Rudolph's 3-in-1 tool there is no saves and no roms loaded in the Psram or Nor.
any help would be much appreciated as i backup my saves and with the app you cant seem to.
