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.

FreeBIOS fallback for DS mode (NTR), while DSi mode requires all native files.
|
|
Libretro fork based on melonDS ~0.9.x era, validates size only.
|
|
Upstream adds CRC32 validation on BIOS files (MemConstants.h).
|
|
DSi SD card emulation controlled by melonds_dsi_sdcard core option.
