Hi, I'm currently looking foward to buying an M3 Real for my DS Regular. However, I'd like to know, what slot 2 exactly works with the GBA SP, and how? I heard this one, the 3in1 might work, but I'm wondering, how do I get data to the card (is it as simple as just booting up my ds and copying it off of the M3s SD card to the slot?), and will it work with an ordinary GBA SP, will it only play GBA roms (or can it use GBC?), and will it give me a boot menu if I have multiple GBA roms as well? Also, as a side note, I'd also like to hear the compatiblities through emulation on the M3 Real itself. Thanks in advance. EDIT : Also, I'm wondering, is this the best slot 1 card like I've heard, or should I aim for the cyclo? Keep in mind I want to play homebrew, and develop it as well.
