Each libretro profile records version_basis and core_version is read there at its pin. snes9x states 1.63 in snes9x.h, nestopia 2.0.0, mgba 0.11.0, vice 3.10, atari800's libretro tree 7.0.0. Cores whose build takes its version from git carry the nearest tag in describe form (flycast v2.7-90-ge88b0ce, ppsspp, duckstation, gearcoleco), placeholders copied from .info files (Git, SVN) are replaced by the code's statement, and a code that states none is null with kind none.

notes: |
|
|
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() (platform/libretro/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" (platform/libretro/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
|
|
(platform/libretro/libretro.cpp:258). Content is loaded either via the libretro data buffer
|
|
or full path depending on the _NEED_FULL_PATH_ compile flag.

|
|
note: |
|
|
.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.

|
|
note: |
|
|
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 (platform/libretro/libretro.cpp:517-736).
