+# 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/

-# IPL ROM loading (memio.c:88-116):
-#   ROM_TYPE 0: uses built-in default IPL (575 bytes, basic boot stub from defipl.res)
-#   ROM_TYPE 1 (X1): loads xmil/IPLROM.X1 (32 KB)
-#   ROM_TYPE 2 (Turbo): loads xmil/IPLROM.X1T (32 KB)
-#   ROM_TYPE 3 (TurboZ): loads xmil/IPLROM.X1T (32 KB, same file as Turbo)
-#   If the file is missing, the core falls back to the built-in default IPL.
+# 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 (font.c:90-127, fontx1.c:70-123):
-#   font_load() calls x1fontread() which looks for font files using fontopen().
-#   fontopen() resolves paths relative to the working directory (file_getcd()),
-#   which in libretro context is the xmil subdirectory.
-#   Built-in defaults (defrom_ank, defrom_txt) are used for basic ASCII rendering.
-#   External font ROMs add full Japanese character support.
+# 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.
 #
-# The .info file only lists IPLROM.X1 and IPLROM.X1T as required BIOS files.
-# Font ROMs are optional -- the core renders basic text without them but Japanese
-# kanji display requires the external font files.
+# .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).
 
 notes: |
   Place all files in: <system_dir>/xmil/
   The core selects between IPLROM.X1 and IPLROM.X1T based on the "X1_ROMTYPE"
-  core option. A built-in fallback IPL exists but lacks full boot functionality.
-  Font files are optional; without them, kanji/JIS characters won't render.
+  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).
