I bought my son a DSi for xmas; he's been sporting a regular DS and a DSTT for awhile. I tried copying his save file from New Super Mario Bros from the DSTT and put it on the M3i, but the M3i "doesn't see it." My Google skills are weak; I can't find anything that says DSTT saves won't work on the M3i. I know the M3i I bought is a "knockoff"... but all the ROMS we have seem to play fine. Any suggestions?
