Guys, really need some help on this. Like mentioned, I got an old 3DSXL with 4.4 and Gateway cards. These are what I've done so far: 1. I already installed Rxtools and this is my launcher for most of the time since I don't have to carry Gateway cards all along. 2. I've followed this tutorial installing patch AGB_FIRM on my Nand with FBI while running Rxtools emunand mode (my emu and sysnand is linked, supposedly ) So far, none of my GBA VC or DSi ware work . They either give me black screen or Software closure notification whenever launched. I just wonder if I have to install AGB_FIRM into my Nand while running Rxtools sysnand mode instead. By the way, is there any way I can stick my Mset profile exploit with this 4.4 3DS, I came across the Mset sticking tutorial but it seems to only work on N3DS. Any help is appreciated.
