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: |
|
|
FCEUmm (FCE Ultra mappers modified) is a NES/Famicom emulator forked from
|
|
FCEU Ultra by CaH4e3. FDS games require the FDS BIOS ROM (disksys.rom).
|
|
Game Genie emulation requires gamegenie.nes when the core option is enabled.
|
|
An external palette file (nes.pal) overrides the built-in palette when the
|
|
core option is set to Custom.
|
|
|
|
File path construction: src/general.c FCEU_MakeFName() joins the system
|
|
directory with each filename directly - no subdirectories.
