So last night I installed a9LH and installed Aureinand over Reinand. When I installed it I originally kept my 10.7 emuNAND and 9.2 sysNAND with unlinked nands. I wanted a9lh because I read about not having to install GBA games on both sysNAND and emuNAND. Everything was fine, then I tried to install a CIA version of Pokemon Leaf Green on emuNAND. I made sure to install patched AGB_FIRM onto my sysNAND, but when I load the game I get an "An error has occurred... turn off your 3DS." So I went into sysNAND and installed the CIA of Leaf Green there as well. I was then able to boot into Leaf Green through emuNAND, but the same error occurred when trying to boot the game through sysNAND.
I decided I was going to remove the emuNAND partition and only use sysNAND with a9lh. Long story short, I flashed my emuNAND over to my sysNAND and accidentally removed a9lh in the process... I recovered though! I had to downgrade 10.7 sysNAND to 9.2 and then I restored my 9.2 sysNAND backup using Decrypt9 just to be safe. I then reinstalled a9lh with the same 9.2 sysNAND, renamed nand.bin on the SD card, back up with no emuNAND. I then injected FBI through health and safety, set up HBL, and updated a9lh sysNAND to 10.7. I installed the AGB_FIRM once more and installed Leaf Green again! I still have the same problem though. When I load the game, I get , "An error has occurred..." Any ideas how I can get this working? The main reason I installed a9lh was for the improved GBA installations...
