What does gba rom patching mean in the info mentioned? Does the AKAIO 1.7 patch gba roms to be played on Acekard2i? because I don't want to buy a Supercard DSTWO(more expensive)
No. That's only for use with a slot-2 flashcart like the EZ Flash 3-in-1. You can't emulate GBA on an AK2.1/2i without an EZ Flash 3-in-1. By the time you buy the two of them together, you might as well buy the SuperCard DSTwo.
