NTR Launcher doesn't work with every flashcart, but it's worth a try.B9S doesn't influence compatibility, CFW does
The newest Luma allows (in theory) for booting any DSi-compatible flashcard directly from the Home menu,
even then *every* slot-1 DS flashcard can be run through the "NTR Launcher" homebrew by Apache Thunder
unless the flashcard is bricked, of course
If nothing at all appears over the card slot icon, either the flashcard is broken or it's poorly fitting (try to cut a rectangle or two of paper, disassembling the flashcard, and putting them between the front half of the case and the board, behind the pins)I also have luma3ds and there's nothing on the home menu, so you think it's probably bricked?
