Okay, let me make sure I understand what this does completely.
I can load homebrew .nds ROMs from the SD card, but not retail ROMs.
I can insert my DSTT card into my 3DS and load ROMs from it, including retail ROMs.
I can only get to a single ROM on my DSTT, and it has to be named "game.nds"
Is this all correct? Is there any way to access YSMenu on my DSTT, and use that to get to my games?
Forgive me if these are dumb questions, but I promised my old DS Lite to my little brother as soon as I got to where I could use my flashcard in my 3DS, with the added condition that if I could get it to where I didn't need my flashcard anymore, I would load it up with the types of games that he likes, and let him have that as well. If I have to get into the MicroSD every time I want to play a different game in order to rename files, then I think I'll try to wait just a bit longer to see if that restriction gets removed later on. If I don't, I have enough actual carts that I can probably give him my DS and he can play with it as-is until I can give him the flashcard as well.
