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 the last GPLv3 release of redream (inolen) before it went closed-source.
|
|
The core has HLE bootstrap -- when boot.bin is missing, bios_invalid_instr()
|
|
traps at PC=0x0 and calls bios_boot(), which loads IP.BIN and 1ST_READ.BIN
|
|
directly from disc, sets up syscall vectors, and starts execution at 0xac008300.
|
|
|
|
The fork sets appdir to the RetroArch system directory root
|
|
(retro_host.c:216-217), unlike the upstream which appends /dc
|
|
(upstream retro_host.c:196-198). The .info declares dc/ prefix paths, the
|
|
layout the upstream reads.
|
|
|
|
boot.bin is validated against four known MD5 hashes (boot.c:25-30).
|
|
Validation failure logs a warning but the core continues via HLE.
|
|
|
|
flash.bin is read/write. If missing, bios_validate_flash() resets all
|
|
partitions to defaults. Saved back to disk on shutdown (flash.c:197-199).
