Custom OS for the FunKey S / Q36 Mini / RG Nano

New

• [Emulation] Default emulators have been replaced by PicoArch with Libretro cores in RetroFE and GMenu2X for better performance, compatibility and accuracy. Please read below before continuing:
  • Save states from the original emulators may not be compatible with the Libretro cores but game saves should (put your .sav files into FunKey/.picoarch/data/CORE_NAME/). So please do NOT install this update if you want to keep using your old save states!!!
  • Put your BIOS (PS1, Mega-CD, PC-Engine CD-ROM, GBA...) in FunKey/.picoarch/system/.
  • The Libretro cores are stored in Libretro/cores/, you should not delete them unless you get a more recent version, otherwise default emulators won't work anymore both in RetroFE and GMenu2X. However, you can add your cores to this folder and use PicoArch to launch them.
  • Libretro core list:
    • Game Boy/Game Boy Color => Gambatte
    • NES => FCEUmm
    • Game Boy Advance => gpSP
    • Super NES => Snes9x2005

• [Stats] Replaced swap size by CPU temperature in system_stats (L+R+Select).
• [PicoArch] Real-time clock is now supported (Gambatte, gpSP...) thanks to @neonloop.
• [RetroFE] Added Artbook-sml theme (author: @s4ilence).
