Default Emulator

By default MustardOS uses the fake-08 libretro core. This is only the default because it doesn’t require you to purchase the native PICO-8 application. We strongly suggest you purchase the native application to support this wonderful system!

PICO-8 Emulator Files

Native PICO-8 is now supported!
Starting with MustardOS Banana, the pico8 files can go in your MUOS/bios/pico8 on either SD1 or SD2 depending on where you’ve chosen to put those. Older version of MustardOS require the files here: /MUOS/emulator/pico8. The files required to run PICO-8 natively are stored on SD1 in the /MUOS/emulator/pico8 folder.
In order to use native PICO-8 you’ll need to place your own purchased binaries in there.
You will need a copy of the following files from the Raspberry Pi version:

  • pico8_64
  • pico8.dat

You can now drop your official PICO-8 zip into /ARCHIVE on either SD Card and install using the MustardOS Archive Manager. The file is named along the lines of pico-8_ver_raspi.zip with ver being replaced with the current PICO-8 release. The extension will need to be changed to .muxzip firstly to be recognised.

Once you add your purchased files from Lexaloffle you’ll need to set MustardOS to use the PICO-8 External emulator.

  • Browse to where your PICO-8 games are in MustardOS content explorer.
  • Press select on any of the items and change core.
  • Select PICO-8 (External) and press X to set this core for the whole directory!
