Incompatible

The recommended flashcards are DSTT and Acekard 2i (and R4 Ultra too, since that's an ak2i clone).If you want perfect game compatibility, get the SuperCard DSTWO/DSTWO PLUS. The only downside is that it drains your system battery faster.If you have a flashcard that works with @Apache Thunder 's NTR Launcher, fell free to request it here.Be sure to specify which build you're using (Normal or Alt), and if RESETSLOT1 is set to 0 or 1 in "sd:/nds/ntr_launcher.ini".
