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: |
|
|
Fork of higan v094 by Alcaro. Restores HLE for coprocessor chips removed
|
|
in v094, adds firmware_appended support and SuperFX overclocking.
|
|
Three profiles: accuracy, balanced, performance (PPU differs, not firmware).
|
|
Core option bsnes_chip_hle (default LLE, requires bsnes_violate_accuracy)
|
|
controls HLE/LLE at runtime. ref: target-libretro/libretro.cpp:428-442
|
|
|
|
Firmware loaded from system_dir via file::exists + mmapstream.
|
|
No hash or size validation on any firmware file.
|
|
ref: target-libretro/libretro.cpp:242-264
|
|
|
|
firmware_appended: firmware can be appended to end of ROM file.
|
|
ref: ananke/heuristics/super-famicom.hpp:83
|
|
|
|
SPC700 IPL ROM (64 bytes) is embedded in the binary.
|
|
ref: target-libretro/libretro.cpp:39
|
|
|
|
Upstream higan v094 by byuu (2014, site defunct). Mercury preserves v094
|
|
code with HLE additions documented in changes.diff at repo root.
