Apart from the obvious that the DSi has an SD slot and no GBA slot I was under the impression that the DSi and the DS lite were the same as far as any DS software running on them were concerned. I have just loaded a Megadrive/genesis emulator ( http://www.workingdesign.de/projects/jenesisds.php ) onto my AKi card.. it works fine on the DS lite, but when I put my card into my DSi, the emulator loads and lets you select a ROM to load.. then it hangs.... On both machines the ROM loads and the ROM information is shown at the bottom of the screen but it then hangs on the DSi but not the DS lite. This homebrew was written when the DSi wasn't around and that leads me to wonder if there are any other games or homebrew that doesn't work on the DSi ( Excluding GBA reliant games like Guitar Hero ). I know there is differences in the DSi hardware but I would have thought for backwards compatibility a program designed for the DS would have run no trouble.. Any one else had any DSi / DSi incompatibilities ? Hope this hasn't been discussed before, I did a quick check first.
