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.

|
|
Based on multiple snes9x forks (uosnes, snes9x2005), optimized for slow hardware.
|
|
All coprocessor data (DSP1-4, CX4, SuperFX, SA-1, SPC7110, OBC1) is HLE with
|
|
embedded ROM tables. No external coprocessor firmware needed.
|
|
BS-X BIOS loading controlled by core option chimerasnes_bsx_bios (default: skip).
|
|
retro_load_game_special() returns false (no subsystem support).
|
|
.info firmware_count absent (= 0), under-declares: code loads 2 files.

Tries BS-X.bin first, then BS-X.bios as fallback.

Size must be BIOS_SIZE (0x100000). Many BS-X games run without it.
