v4.2

• Fixed ARM11 access to chainloaded payloads (like CakesFW).
• Made the memory operations faster, as they're now better optimized thanks to -O3 (thanks TuxSH!)
• Added TWL/AGB FIRM patching/SD loading for New and Old 3DS (thanks to mid-kid of CakesFW for the reboot patch revision, and to TuxSH/Steveice10/others who worked on the patches for making it possible!). Please note that if you're booting a 9.0/9.2 NAND with 9.0 FIRM the reboot patch can't be applied (to not screw up exploits), and so the patched AGB/TWL won't work. You can also optionally enable the original GBA boot screen in the config menu.
• Fixed the second emuNAND patched FIRM still getting created.
• Made L not needed to load most payloads. You can now launch these payloads: up.bin, down.bin, left.bin, right.bin, x.bin, y.bin with only the corresponding button, and select.bin and r.bin with L+SELECT and L+R respectively. default.bin is now launched with just START or if the the button's matching payload doesn't exist.
• Added the possibility to configure the brightness for the built-in screen init. This is valid for all the instances in which AuRei inits the screen (config menu, payloads, errors). The 4 levels are respectively level 5, 4, 3, 2 from the 3DS OS. Just use Up to get to it in the config menu and use A to toggle.
• Code cleaned up and made more readable.
