Anybody else having problems with their roms on the new backlit GBA SP? The roms I have on my X-rom 512 all played pefectly fine on my old GBA but when I upgraded to the new GBA SP, I am encountering game freezes. More specifically with Metal Slug Advance. I can play up to the point until I get to the end of the first level and then it freezes - so I put the x-rom back into the old GBA and can beat the level and save it and then continue on to the next mission on the new GBA and then it freezes again.
Is anybody aware of anything that Nintendo may have done with the new GBA's? Most of the other games I have played work fine.
