DSi roms and DSi Cards

Do DSi roms work on DSi cards yet? Might sound like a dumb question, but some website said something along the lines of cards not being able to use DSi roms because they're locked to a DSi cart or... something. I don't exactly remember the wording... X_X

i haven't seen dsi only games yet just the dsi shop's

DSi roms do not work on dsi flash cards because the dsi mode hasn't been unlocked yet.

just get a R4i? dur, or otherwise known as R4pro?

DSi Ware are locked to the DSi that downloaded them from the Nintendo store. DSi Enhanced games will work on few flashcarts/emulators which contain advanced DSi features, but they still are in the .nds format. DSi exclusive games would have a .dsi extension.
