EZ-Flash USA Forum

Silly question, I realize, but thus far, my endeavor to find the answer to this question has proven futile. I know it supports GBA roms on the Nintendo DS, but what if I wanted to get this flash cart solely for the sake of playing GBA rom's on a GBA?

To be specific, a Gameboy micro, if that makes any difference at all.

It will work absolutely fine for that- anything that has a GBA slot the EZ4 (and for that matter any other GBA flash card) will run in it. GBA, GBA SP, GB micro, GB player, DS or DS lite it does not matter.
