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.

Chips-fr's libretro port of UAE4ALL, an Amiga 500 emulator with the FAME
|
|
68000 core. It reports itself as uae4all 0.7 and loads adf, adz and zip
|
|
images (libretro/core/libretro-core.cpp:425-428). Recalbox builds it from
|
|
this commit with Makefile.libretro at tag 10.1.1
|
|
(recalbox package/libretro-uae4all/libretro-uae4all.mk:8-9, 19-22).
|
|
Its two patches switch the CPU core to Cyclone and lower the cycle unit,
|
|
neither touches file loading.
|
|
|
|
The Kickstart path is fixed: retro_init takes the frontend system
|
|
directory (libretro/core/libretro-core.cpp:309-313) and the option update
|
|
joins it with A500_ROM, kick34005.A500 (libretro/core/libretro-core.cpp:76,
|
|
85-88, 284). No other name is tried. The joined path is cut at 63
|
|
characters (romfile[64], src/disk.cpp:50). Recalbox sets the system
|
|
directory of every Amiga system to bios/amiga/bios
|
|
(recalbox projects/configgen/configgen/generators/libretro/libretroRetroarch.py:517-519).
|
|
|
|
read_kickstart (src/memory.cpp:853-888) fills a 512 KB ROM space
|
|
(src/include/memory.h:53). It accepts 8 KB (A1000 bootstrap), 256 KB
|
|
(mirrored) or 512 KB, and rejects any other size. A checksum mismatch only
|
|
writes a log line (src/memory.cpp:836-851). No hash is checked, so any
|
|
Kickstart of an accepted size works under that name. An AMIROMTYPE1
|
|
header is skipped but decode_cloanto_rom is empty (src/memory.cpp:831-834,
|
|
860-865), so encrypted Amiga Forever ROMs do not boot and rom.key is never
|
|
read. extfile is never set, so no extended ROM is loaded
|
|
(src/memory.cpp:890-896).
|
|
|
|
Without the ROM the core shows "No Kickstart file found." and runs the
|
|
UAE ersatz replacement (src/memory.cpp:1234-1240, src/ersatz.cpp:35-41).
|
|
It stubs a few exec calls and boots the bootblock in DF0 with read-only
|
|
trackdisk access, so only self-booting trackloader disks start, and the
|
|
core quits with no disk in DF0 (src/ersatz.cpp:75-112).
|
|
|
|
A .uae content file is read for its floppy0= and floppy1= lines only
|
|
(libretro/core/libretro-core.cpp:101-128, 281-282). The data/ assets
|
|
(menu images, click.wav, music.mod, vkbd bitmaps) belong to the
|
|
standalone GUI. Makefile.libretro defines NO_VKBD (Makefile.libretro:28),
|
|
which stubs vkbd_init (src/vkbd/vkbd.cpp:17-23), and does not compile
|
|
src/menu/menu.cpp or src/sound.cpp (Makefile.libretro:100-132). The
|
|
bios/uae_data folder the Recalbox package creates is never opened by this
|
|
core (recalbox package/libretro-uae4all/libretro-uae4all.mk:27).
