I have a ds lite, my nephew has a regular DS, My ds is flashed, has an M3 lite. his is stock. using my cart, my "roms" and using single cart mode in metroid, and ridgeracer. he connects downloads and then it fails. did the same thing with another plain ds. Then i gave him the m3, and used a passkey2 on his and let him host, same roms, worked fine for me to download with the lite and play? Anyone know why this is? Could it be something that was done with the flashme?
