+
+# X Millennium (XMIL) is a Sharp X1 series emulator by yui. The libretro port
+# supports X1, X1 Turbo, and X1 TurboZ models via the "X1_ROMTYPE" core option
+# (values: X1, TURBO, TURBOZ; default: X1 = ROM_TYPE 1).
+#
+# All system files go under: <system_dir>/xmil/
+# (libretro.c:597 builds the path as "<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.
+#
+# 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.
+#
+# 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.
+
+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.
