Polari3DS by Alexyo21 is a modification based on the official Luma3DS v13.0. It comes with a custom boot.3dsx with pirate theming.

List of changes

Restored UNITINFO and enable rosalina on safe_firm and disable arm11exceptions and also cut down wifi options on the luma config menu

• Added shortcuts:
  • Press start + select to toggle bottom screen (nice when you watch videos) inspired by This, limit on o2ds, cause hardware register for up and down lcd are the same looking for new test though... also you can toggle even up display you have to change scrren brightness and with button Y you can change which screen you wanna toggle, it only works in there.
  • Press A + B + X + Y + Start to instantly reboot the console. Useful in case of freeze, but don't complain if your sdcard get corrupted because of this. also this needs to be activated in the hidden conf.(lumae.ini) also enabling ignore err disp will make your console ignore some hardware error be careful your hardware is still damaged... also for new3ds you should enable the rosalina susmodule (maybe not so sus...) in safe firm in hidden conf menu.
