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.

|
Community fork of Mednafen's Lynx module (itself based on Handy by
|
|
K. Wilkins) for libretro. Loads lynxboot.img from the system directory
|
|
at game load time (libretro.cpp:191). CRom constructor reads exactly
|
|
512 bytes (rom.cpp:50-78). If the file is missing or undersized, the
|
|
ROM array is filled with 0x88 (DEFAULT_ROM_CONTENTS) and the core
|
|
continues without error, but games will not boot without the real boot
|
|
ROM. No hash validation is performed on the BIOS at load time.
|
|
The cart database in cart.cpp includes the BIOS CRC32 0x0d973c9d for
|
|
identification purposes, not validation.
|
|
Upstream Mednafen throws an exception if the BIOS is missing or
|
|
undersized, while the libretro port silently degrades. Upstream supports
|
|
custom palette loading (lynx.pal), but the libretro port does not.
