So, I've been wondering if there's a way to decrypt a R4's _DS_MENU.dat file and rename it to a .nds file so it can run perfectly on YSMenu. I tried using r4denc and managed to do so, but when I load the .nds file with YSMenu I just get 2 black screens. Before someone asks why would I want the R4 firmware if I already have YSMenu working...well, a game I want to play (Rune Factory 2 undubbed) doesn't work but it does work in a R4. Weird, huh? Anyone willing to help?
