A Pico 8 player for homebrew consoles. The goal of Fake-08 is to make Pico-8 games playable on platforms that aren't officially supported. Latest release includes releases for Nintendo 3DS, Nintendo Switch, Sony PS Vita, Nintendo Wii U, the Miyoo CFW for bittboy and similar consoles, and the Miyoo Mini.

Originally created by Lexaloffle Software, PICO-8 is a virtual machine and game engine. It is designed to be a fantasy video game console that mimics the limited graphical and sound capabilities of 8-bit systems of the 1980s.

Installation

Download VPK and install with VitaShell on Vita.

Pico 8 cart files go in the p8carts/ directory of your memory card (memory card at ux0:/ on Vita). .p8 text file carts and .p8.png image file carts are supported.

User guide

You can download games from the Pico-8 BBS in png format. Click on the Cart link in the lower left of the game view, and save it into your p8carts directory. Below are some games that you can try out.

If you are trying to play a multi cart game, it should be noted that you must provide all the carts required by the game as FAKE-08 currently does not have cart downloading capabilities. All carts should be placed in the same directory.

See also FAKE-08 Cart Compatibility.

Controls

Left/Right - Cycle through carts on the SD card

Cross - Choose a cart

Start - Pause menu, Exit the currently running cart

R - Cycle between rendering sizes

L+R or Home - Exit the application

Known issues

Latest Pico 8 version v0.2.2 features (sprite fill patterns, text control codes, custom fonts, etc) not implemented yet.

Games using flip() (like tweetcarts) have intermittent problems exiting back to the menu, and may crash the console. Use with caution.

Sound emulation is not perfect, and the noise implementation is noticeably inaccurate. Most of my sound implementation was ported over from Zepto 8. with the exception of the Noise instrument which was ported from PicoLove. It is not 100% accurate, and some games have noticeable clipping/popping.

See Issues page for more specifics.

Release notes.

Credits

• Zep/Lexaloffle software for making pico 8.
• Nintendo Homebrew Community.
• Vita Homebrew Community.
• zepto8 - Probably the best Pico 8 emulator. FAKE-08's audio, tline, and newer png decompression implementations were ported from zepto8, and other parts were heavily influenced. Alsod use a slightly modified z8lua for pico 8 specific features.
• PicoLove - Basis for a previous project - PicoLovePotion - and first learned the basics of Pico 8's API.
• tac08 - A Pico 8 emulator. FAKE-08's sprite rendering and cart parsing is heavily based on tac08, and it uses 0xcafed00d's utf8-util to handle special characters in pico 8 carts.
• LovePotion - An implementation of Love2d for 3DS and switch that served as the runtime for PicoLovePotion, and a great way to make homebrew games for the 3DS and switch. Also use a modified version of their static Logger implementation.
