I have: Gameboy Player DS Lite DS Phat DS-Xtreme I want to get: EZ-Flash 3 in 1 (GBA Sized). Based on this, I assume the device will work in any GBA slot I put it into. What I really want to know is, does the GBAEXPLoader work with my DS-Xtreme, and the GBA sized version of the 3 in 1. (As a side note, getting this to work with my DS-Xtreme is not very important. I will be flashing only 1 game to the device and can borrow an R4). Thanks.
