2.6 installs well for me regardless of agb_firm
personally i cant get gba to work at all though (even on 2.5)
100% sure im downloaded correct files with 3dnus, and patc seems to work but installing .cia to nand does nothing
every game gives me error screen on launch
have original black 3ds xl if that matters (unlinked nand)
if you delete the agb_firm in FBI it doesnt seem to auto reinstall it on 2.6 btw
