I have just purchased a Nintendo DS Lite (Cobalt Blue) from a local futureshop today, and have ordered a DSTT card online off of ebay. Then i found out i need a cart to be able to play GBA games as well. I've been trying to search/read on how to do this, even youtube'd tutorials but it still seems unclear to me. I'm looking to pick up an EZ Flash 3-in-1 Expansion cart, is this compatible with the DSTT? Will i be able to run DS & GBA games with both of these items?
