I have Luma 3ds, and both Sysnand and Emunand are unlinked. When I try to boot the game on Emunand it does what is described in the title. Yes, I installed the Cia in both Sysnand and Emunand, besides of patching the AGB_FIRM as this post describes of course. Do you think the error comes from my inyected GBAs? I didn't inject it myself, so that's a posibility. I tried to uninstall the respective Cias on FBI 2.0. In SD was no problem, but in Nand I don't sure what titles are GBA games since these are shown as black icons on Sysnand and I'm afraid to screw up.
