Default Emulator

By default MustardOS uses Picante8, the MustardOS PICO-8 core, which runs carts through Pickles. It plays .p8 and .p8.png carts without needing the native PICO-8 application, and supports:

  • Save states, including in multicart games and in carts that run their own game loop.
  • Multicart games, where one cart loads another with load() or reads its data with reload().
  • Cart saves through cartdata(), kept in the Pickles save folder.

A game made of several carts, such as Poom, can open as a single item with Set Launch File, described in Folder Launch Files.

FAKE-08 is also available as a libretro core from Core in Content Options. Picante8 is only the default because it does not 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 supported once you add your own purchased binaries. You will need these files from the Raspberry Pi version:

  • pico8_64
  • pico8.dat

Place them in MUOS/bios/pico8 on SD1 or SD2, following where your BIOS files are stored. A MUOS/bios/pico-8 folder copied straight from the purchased download is also recognised.

You can also install the official download through Archive Manager. Rename the pico-8_ver_raspi.zip file, where ver is the current PICO-8 release, to end in .muxzip, copy it to the ARCHIVE folder on either card and install it from Archive Manager.

Once the files are in place, switch your PICO-8 content to the standalone emulator:

  1. Highlight your PICO-8 folder in Explore Content and press X to open Content Options.
  2. Choose Core, then PICO-8 - Standalone or PICO-8 - Pixel-Perfect - Standalone.
  3. Choose the Directory or Recursive scope to apply it to every game in the folder.

Can I use Splore?
