So I used Riku's AGB_FIRM patch in Emunand, since I'm still having trouble running rxtools dev mode for some reason, and my GBA VC games are still returning errors after applying the patch. I used FBI, and I'm sure I installed it to the NAND (within my Emunand). I'm using a 2DS with 10.3 emunand and a 9.2 sysnand. I'm sorry if this's been answered time and time again. Thank you for any solutions.
