Template:Infobox-3DS-Homebrews
fake-08
A Pico 8 player for homebrew consoles. Not related to or supported by Lexaloffle Software. Latest release includes releases for Nintendo 3DS, Nintendo Switch, Sony PS Vita, and Nintendo Wii U.
Usage:
Installation will vary by console and executable type. If it is a console with a homebrew menu (Switch, Wii U, 3DS using .3dsx), place the executable file in the directory with other executables. If it is a console with installable hombrew (3ds with .cia, or PS Vita) install executable (VitaShell on Vita or FBI on 3DS).
Pico 8 cart files go in the p8carts/ directory of your memory card (SD card on 3DS, Switch, and Wii U, memory card at ux0:/ on Vita). .p8 text file carts and .p8.png image file carts are supported.
Launch FAKE-08 either via the homebrew menu or normal system UI (depending on how you installed). Use left and right to cycle through carts on the SD card. Choose a cart using the A (Nintendo consoles) or X(Vita) button. To exit the currently running cart, press Start or + to open the pause menu and select Exit to Menu. Press R to cycle between rendering sizes. Press L and R simultaneously to exit the appication. You can also close it via your console's operating system controls (home button etc).
Building:
All platforms have automated builds set up via GitHub actions using docker images. You can see how those are set up in the .github/workflows directory of the repo.
Building outside of a pre-setup docker container will require a toolchain installation for the platform that you want to build.
For the Nintendo consoles, install the appropriate toolchain from devkitpro (see https://devkitpro.org/wiki/Getting_Started). Switch and Wii U also require the platform specific SDL2 portlibs to be installed.
Building for the Vita requires Vita SDK (see https://vitasdk.org/) to be installed.
Once you have the appropriate toolchain(s) installed, call make followed by the platform name (3ds, switch, vita, or wiiu) to build that platform, or just make to build them all. make clean will clean all files from all platforms.
Building tested on windows using devkitpro's msys2 and Ubuntu (WSL and standalone). Should work on other plaforms as well.

- zepto8 (https://github.com/samhocevar/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. I also use a slightly modified z8lua (https://github.com/samhocevar/z8lua) for pico 8 specific features.
- PicoLove (https://github.com/gamax92/picolove) - basis for my previous project - PicoLovePotion - and where I first learned the basics of Pico 8's API
- tac08 (https://github.com/0xcafed00d/tac08) - a Pico 8 emulator that I leared a lot from. 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 (https://github.com/TurtleP/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. I also use a modified version of their static Logger implementation

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 missing effects, and the noise implementation is wildly inaccurrate. Most of my sound implementation was ported over from Zepto 8 (a much more accurrate emulator) but I didn't want to bring over dependencies that were needed for those parts, and haven't otherwise implemented them yet
Sound currently not supported on Wii U. I also suspect there may be some bugs with peeking and poking multibyte values on the Wii U given its Big Endian architecture, but have not confirmed
Performance is not great on Old 3ds systems. Some games may experience slowdowns on the faster consoles as well. More optimizations are probably possible, but keep in mind that Pico 8 lists a raspberry pi 1 with a 700 MHz ARM11 professor as minimum spec, and the old 3DS's CPU is 268 MHz ARM11. Many games should be playable regardless.
See Issues page for more specifics
Carts
You browse and download carts by using the SPLORE() function in Pico 8 (again, if you have $15 to spend, and you are interested in game dev, it is well worth your money). Once you have loaded a cart that you want to try on FAKE-08, type save Template:Cartname.p8 to save the cart as a text file, then copy that file to your device's SD card.
You can also browse carts on the Pico-8 BBS website, but can only download complete carts in png format. As of pre release v0.0.1.1 Fake-08 should load and play png carts provided they don't use any other unsupported features. You can download p8.png carts from the Cart link in the lower left of the game view, and save it into your p8carts directory.
Other Notes
Compatibility is improving, but not perfect. I think many carts should work, but this is still a project in the early stages, and it is my first real foray into C or C++ development and low level game dev in general. I'm mostly doing this project as a fun way to learn.
Feel free to write up any issues you come across, and attach or link to a cart that reproduces the issue. My main goal is to improve compatibility with Pico 8, and then improve speed of carts that are too slow on New 3DS systems.
