I have a problem with a bunch of ROMs that won't work at all on the GBA extension to the M3Real. When I try to boot any of these games, there's a progress bar at the bottom of the screen, but when the game is booting there's no Nintendo logo, iow the same behaviour as if there's no cart inserted into a GBA. NDS Slot 2 booting works fine. First I though it had to with the recasing of the lite cart, but I don't think that's the problem. I've also borrowed a G6 GBA flash cartridge from a friend, which works in exactly the same way. (Some ROMs are working, some are not, NDS Slot 2 boot works) When booting the G6 cart in pure GBA mode (Ie not opening a ROM from within M3, but rather using the G6's own menus) everything works as it should. Here's my compatibility list: Not working (No Nintendo logo) Super Mario Advance 2 - Super Mario World Mario Kart - Super Circuit Bomberman Tournament Sonic Advance Tony Hawk's Pro Skater 2 Pocketnes Working Mortal Kombat - Deadly Alliance Puyo Pop Tony Hawk's Pro Skater 3 If it matters, I'm using a DSPhat with M3 Manager V2.6 X.
