- 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.

- To override the last used boot mode on soft reboot, you only need to press A if you want to boot to the default option. Holding L(+payload button)/R is enough for the other modes.
- Added version number to the config menu
- Replaced the memsearch algorithm with a faster one
- Integrated 3ds_injector from @yifanlu. This brings us region free and all the other FreeMultiPatcher patches. Other than that, you now have the possibility to display the currently booted NAND/FIRM in System Settings!
- Rewritten most code for the config menu. You now can navigate to the first/last options with left and right.
- You can now choose the 9.0 FIRM to be default in the config menu. This will essentially switch "no buttons" and L in both modes.
- You can now choose the second emuNAND to be default in the config menu. This will essentially switch "B is not pressed" and "B is pressed".
- When the second emuNAND is booted, it will persist like the other boot options on soft reboot
- Bugfixes

v3.13:
- Due to requests, changed the payload chainloading to use L+R just for the default payload, and L+button for the other ones. The default will be loaded if the corresponding payload doesn't exist.
- Increased the brightness of the built-in screen init.
- Blocked Safe Mode (L+R+Up+A) access on A9LH, as using it would brick the console (N3DS) or remove A9LH due to the reboot to SAFE_MODE FIRM.


v3.12:
- Introduced a configuration menu which can be called by holding SELECT on boot, which replaces "flags". It appears automatically when the config file is not found, and it can be used to toggle the options that were "flags" previously.
- AuReiNand now prints error messages before shutting down.
- To reduce SD card accesses and make the program more newbie friendly, emunand.bin, reboot.bin and loader.bin have been merged into the main executable.
- FIRM patching has been made slightly faster (only applies if pre-patched FIRMs aren't used) by removing two memory searches.
- AuReiNand will auto-delete the pre-patched FIRMs when you switch to/from A9LH or, in the future, new FIRM patches are added.
- Payload chainloading now also works from CakeBrah.

I'd like to thank mid-kid at CakesFW for the screen printing code :)
