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: |
emux is a multi-system emulator by Sebastien Ronsse. BIOS and cartridge
code identical between upstream and libretro fork (only difference: libretro
adds g_ram_data/g_ram_size exposure in mach/sms.c for RETRO_MEMORY_SYSTEM_RAM).
BIOS loaded via file_map(PATH_SYSTEM, "bios.sms", 0, BIOS_SIZE) in
sms_mapper_init (controllers/mapper/sms_mapper.c:162-165). Returns false on failure, no HLE
fallback. Mapped at 0x0000, overlays cartridge ROM until bios_disable bit
set in slot control register (controllers/mapper/sms_mapper.c:79-82).
No hash validation. Code accepts any file >= 8192 bytes.
is_experimental=true. No save states, rewind, or netplay.
