Hi there. Recently bought a 3DSXL and am running firmware 188.8.131.52. I'm looking to buy a flashcart that supports GBA and DS roms. Is there a DStwo card that is for sale that works with v4.5 out of the gate, or do I HAVE to update an older card on a different DS system? I don't have another DS so that's an issue :/ Also, for clarification, the DStwo card does support GBA and DS roms, correct?
