some DSi games work on some newer flashcards like Acekard2i and SupercardOne in the DSL, although there are obvious issues with the dsi features that that the DSL dont have like the camera.
For example Assassins Creed II - works on Acekard2i, but the part which allows you to have your picture on wanted posters throughout the game will not work. so this is a very small DSi part and wont spoil you playing the game, other games may make even more use of DSi features which will make it impossible to play on DSL even if they load up.
But if you have a old R4 its less likely that they will even load, you can sometimes find patched DSi games will work on R4 running Ysmenu, but rarely.
