I must be doing something wrong. I followed all of the instructions on the dsi guide site and I cannot play GBA games. I installed TwilightMenu as the instructions described, and I put the GBA rom in the ROM folder. I also have the bios.bin on the root of my SD card. But when I go to the GBA folder on Twilight Menu, my GBA rom does not show up. Does anybody know what I might be doing wrong? Game Boy games show up just fine under GB so I am not sure what I could be doing wrong. And no the ROM is not in .zip format. It's a .gba. Thanks in advance for any help!
