+notes: |
+  PicoDrive is a fast Mega Drive / Genesis emulator with Mega CD, 32X, Master
+  System, Game Gear, SG-1000 and Sega Pico support.
+
+  Mega CD / Sega CD games require a region-matching BIOS file. The core searches
+  the system directory for each name in order, trying .bin then .zip extension,
+  and uses the first file found. If no BIOS is found, CD games fail to load with
+  PM_BAD_CD_NO_BIOS. MSU-MD games can run without BIOS.
+
+  BIOS filename search order (platform/libretro/libretro.c:1265-1329):
+    US: us_scd2_9306, SegaCDBIOS9303, us_scd1_9210, bios_CD_U
+    EU: eu_mcd2_9306, eu_mcd2_9303, eu_mcd1_9210, bios_CD_E
+    JP: jp_mcd2_921222, jp_mcd1_9112, jp_mcd1_9111, bios_CD_J
+
+  32X BIOS files (m68k, master SH2, slave SH2) are fully optional. The core
+  has built-in HLE that generates replacement code at startup when the external
+  BIOS pointers are NULL (pico/32x/memory.c:2200 get_bios(), pico/32x/32x.c:172).
+  The libretro frontend does not expose any 32X BIOS loading path. Only the
+  standalone platform code references 32X_M_BIOS.BIN / 32X_S_BIOS.BIN, and
+  that code is currently disabled (#if 0 in platform/common/emu.c:1529).
+
+  Master System, Game Gear, SG-1000: no BIOS file loaded. The core initializes
+  VDP registers and RAM to simulate post-BIOS state (pico/sms.c:1080-1096).
