System.dat pins the 2 KiB X1 font as xmil/IPLROM.X1T, where xmil reads a 32 KiB Turbo IPL. A held copy of the exact size a profile declares now proves its claim against a file of another size, so the existence packs ship the IPL. The font's duplicate under the IPL name is removed.

# 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 incorrectly says "8x8 Font ROM" (actually 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).
