A few of my ROMs, namely "Mario Tennis Advance" and "Banja-Kazooie: Grunty's Revenge" will go through the opening screens and menus, and then at a certain point just resets back to the white Gameboy screen. For the vast majority of roms, Gameboid runs perfectly fine. Is their a known issue with these ROMs, or something i'm missing? I get mine from coolroms.com
