Abdessamad Derraz e7aa9e870b fix: state libretro core versions from their code
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: |
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.

note: |
Loaded by BSX_LoadBIOS() from system_dir when core option
chimerasnes_bsx_bios is set to 'load' (default: skip).
Tries BS-X.bin first, then BS-X.bios as fallback.
Size must be BIOS_SIZE (0x100000). Many BS-X games run without it.

Loaded by LoadSFTBIOS() from system_dir when Sufami Turbo game
detected (BANDAI SFC-ADX header at ROM offset 0, memmap.c:833).
Reads 0x40000 bytes into Memory.ROM. No validation performed.
