- Move emuNAND hook to ITCM, fixing previously untested emuNAND support for 5.0 (and possibly more versions). This was a very long-standing bug - Fix booting on versions 4.x to 8.x, and restore full support for 5.x to 8.x. All Arm11 custom sysmodules and k11ext have been disabled on 4.x because the Luma3DS v13.0 changes couldn't be ported (this means no Rosalina and no region-free and such, and while I could restore some of the functionality, you should just update *after* installing Luma, like you've been instructed to)
