I recently (like a couple days ago) installed A9HL onto my N3ds and am currently on 11.0. The problem that I had was that when I tried playing Gba games i installed using FBI they would just go to a black screen. I also found the same problem to happen when I try using my R4I RTS card. I'm not sure what the problem is as i also have a O3ds with a9hl that boots both GBA and the flashcart perfectly. Any help would be appreciated.
