I heard that some people gotten the DSTT to work on the DSi? How did they get this to work? Also I know that the DSTTi catridge has some new firmware in the cartridge. I was wondering if some can uploaded here? I not talking about the V1.09 that goes on the flashcard. I talking about the one thats in the cartridge itself. If you use the wifibackup, when it ask to insert a cartridge you insert the DSTTi with no memory card, and it will read the firnware on the cartridge. Maybe there is a way to flash that memory into regular DSTT cartridge to get them to run on the DSi.
