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.

# X Millennium (XMIL) is a Sharp X1 series emulator by yui, ported to libretro
|
|
# by r-type. Supports X1, X1 Turbo, and X1 TurboZ models via the "X1_ROMTYPE"
|
|
# core option (X1 = ROM_TYPE 1, TURBO = 2, TURBOZ = 3).
|
|
#
|
|
# SUPPORT_TURBOZ is not compiled in the libretro build (compiler.h), so TurboZ
|
|
# extended color modes are unavailable. ROM_TYPE 3 still selects IPLROM.X1T.
|
|
#
|
|
# All system files go under: <system_dir>/xmil/
|
|
# retro_init() builds: retro_system_conf = "<system_dir>/xmil" (libretro.c:597)
|
|
#
|
|
# IPL ROM loading (memio.c:87-121):
|
|
# biosmem is initialized with defaultiplrom (575-byte boot stub from defipl.res).
|
|
# ROM_TYPE >= 1: loads external IPL ROM into biosmem, overwriting the stub.
|
|
# ROM_TYPE 1 (X1): xmil/IPLROM.X1
|
|
# ROM_TYPE >= 2 (Turbo/TurboZ): xmil/IPLROM.X1T
|
|
# Path built explicitly: sprintf(rtmp, "%s%c%s", retro_system_conf, slash, iplfile)
|
|
# If file missing, the 575-byte stub remains (limited boot capability).
|
|
#
|
|
# Font loading (fontx1.c:69-122, font.c:89-127):
|
|
# font_load(NULL, TRUE) called from pccore_initialize() (pccore.c:67).
|
|
# Built-in defaults (defrom_ank, defrom_txt from fontdata.c) provide basic ASCII.
|
|
# x1fontread() tries to load external font files via fontopen().
|
|
# Font path resolution uses file_getcd() which defaults to "./" in the libretro
|
|
# port (file_setcd() is never called). Upstream win9x/sdl2 calls file_setcd()
|
|
# to set the working dir. Fonts may not be found from xmil/ in practice.
|
|
#
|
|
# .info declares firmware_count=2 (IPL ROMs only). Font files are not declared.
|
|
# .info firmware1_desc reads "8x8 Font ROM". The core loads IPLROM.X1T as the
|
|
# Turbo IPL ROM.

Place all files in: <system_dir>/xmil/

|
The core selects between IPLROM.X1 and IPLROM.X1T based on the "X1_ROMTYPE"
|
|
core option. A 575-byte built-in IPL stub provides limited boot without the
|
|
real ROMs. Font files add Japanese character support. The libretro port has a
|
|
path resolution quirk where fonts are searched in "./" instead of "xmil/"
|
|
(missing file_setcd call).
