|
|
FAKE-08 is an open-source PICO-8 compatible runtime for running .p8 and
|
|
.p8.png cartridges on platforms where the official PICO-8 binary is not
|
|
available (3DS, Vita, Switch, Wii U, various handhelds).
|
|
|
|
The core retrieves RETRO_ENVIRONMENT_GET_SYSTEM_DIRECTORY in
|
|
retro_set_environment() (libretro.cpp:162-163) but never uses the value.
|
|
No file is loaded from the system directory. The PICO-8 boot sequence,
|
|
global Lua functions, and default cart menu are compiled directly into the
|
|
binary as string constants (p8GlobalLuaFunctions.h, DefaultCart.h).
|
|
|
|
When no ROM is passed (supports_no_game = true), the core queues its
|
|
built-in BIOS cart "__FAKE08-BIOS.p8" (libretro.cpp:751). This is not
|
|
an external file -- it is generated internally by the VM.
|
|
|
|
The core accepts .p8 (text) and .png (cartridge-as-image) formats
|
|
(libretro.cpp:258). Content is loaded either via the libretro data buffer
|
|
or full path depending on the _NEED_FULL_PATH_ compile flag.

notes: |
|
|
.p8 is the PICO-8 text cartridge format containing Lua code, gfx,
|
|
gff, map, sfx, and music sections. .png is the cartridge-as-image
|
|
format where cart data is steganographically encoded in the image.

|
notes: |
|
|
The FAKE-08 VM reimplements the PICO-8 API (128x128 screen, 16 colors,
|
|
4-channel audio, Lua scripting) entirely in C++. The built-in BIOS
|
|
provides a cart browser and error display. Audio runs at 22050 Hz
|
|
with save state support via custom serialization (libretro.cpp:517-736).
