M3 Lite...

Found a DS left on the subway, and it had a M3 Lite ... thing on it (forgive my lack of flashcard knowledge)I already have an R4 and DSTT, but have no experience with the M3 LiteThe MicroSD card goes inside a GBA Flashcard, and there's another card for the DS slot that seems to required to use the flascard.The problem is... I have no idea what to do with it. The save files are .Dat, so when I try to play new games, it says I need to have a save file... but I don't know how to make .Dat files as saves.Also, I'm not sure if i have the latest firmware...Please help me figure these things out ???

You lucky bastard ):Anyways I don't think the slot 1 card is required for the M3 Lite to run. I've got no experience in it too. But one thing though. You lucky bastard ):
