I'm trying to add a game from a flashcard as the instructions in the OP said. I'm currently using an M3 DS Real. However, the "Add game" button in the TWLoader home screen takes me to the flashcard menu where I can launch the game and such. If I select the ROM, it just launches it, it doesn't get added to the TWLoader home screen. Is there something I'm not getting correctly?
On a different note, even though it was buggy and it freezed randomly, launching Pokemon Soul Silver from the SD reminded me how beautiful of a game it is, so I had to search in dusty boxes for my old broken Nintendo DS that had the flashcard still in it. I haven't played it in like 7 years. Thanks for this wonderful app.
