I've tried multiple pokemon diamond/pearl roms on both a sandisk and kingston 1gb micro sd card formated both FAT and FAT 32 on my R4. I can load up each game and tell the pokemon proffesor my name and that i am a boy. Once I am in the game and I go to the save menu it locks up. "Saving a lot of data... Don't turn off the power." will be on the screen along with the music playing in the background for well over 10minutes until i get stressed enough to try and find a "better" rom. Did all of you just load of your roms and it worked perfectly or am I missing a valuable step?
