+notes: |
+  Rolling release tracking mamedev/mame upstream (currently 0.286).
+  99 BIOS root sets. romload.cpp unmodified. No hiscore support.
+  Paths under system_dir/mame/ (artwork, cheat, hash, ini, plugins,
+  samples, crosshair). ROM search: content_dir + system_dir/mame/bios +
+  system_dir/mame/roms. Cheats via per-game XML files.
+
+  BIOS root set names follow current MAME conventions. ZN-based boards
+  renamed from legacy names (cpzn1 → coh1000c, atpsx → coh1000a, etc.).
+  File structure uses vendor-based paths (src/mame/{vendor}/).

+  Frozen snapshot of MAME 0.78 (xmame, January 2003). Stock version without
+  the Plus patches. Targets low-end hardware (Raspberry Pi, SBCs).
+
+  BIOS ZIPs are searched in:
+    1. {content_dir}/ (same folder as the game ROM)
+    2. {system_dir}/mame2003/ (libretro system subfolder)
+    3. {system_dir}/ (libretro system root)
+
+  Data files (hiscore.dat, cheat.dat, history.dat) are loaded from
+  system_dir/mame2003/. Samples from system_dir/mame2003/samples/.
+  All bundled in the repo's metadata/ directory.
+
+  Neo Geo uses 7 official BIOS variants. Universe BIOS is commented out
+  in the stock source (available in mame2003_plus).
+
+  ROM naming follows MAME 0.78 conventions.

 notes: |
-  MAME 2010 is a libretro port of MAME 0.139, released around mid-2010. Compared
-  to mame2003 (MAME 0.78, early 2003), it adds roughly 7 years of MAME development
-  including better driver accuracy, more supported arcade boards, and additional
-  BIOS sets.
+  Frozen snapshot of MAME 0.139 (mid-2010). Sourced from mame0139s.zip.
+  51 BIOS root sets. Upstream comparison (tag mame0139): BIOS root sets
+  identical, romload.c modified (libretro_content_directory), hiscore.c
+  added (not in upstream), cheat.c modified (cheatpath global).
 
-  Key differences from mame2003 (0.78):
-    - 51 BIOS root sets vs ~30 in mame2003
-    - Sega boards: adds Hikaru, Chihiro, Triforce, Naomi 2, Naomi GD-ROM
-    - Namco boards: adds System 246/256/573
-    - Konami: adds Viper, expanded GX support
-    - Philips CD-i support (cdi)
-    - Taito Type X / GNet expanded
-    - Crystal System (Brezzasoft)
-    - More ZN-1/ZN-2/PSX-based board variants (cpzn1, cpzn2, atpsx, etc.)
-    - Neo Geo: same core BIOS set, adds Universe BIOS up to 2.3
-    - PGM: same BIOS ROMs, more game drivers
+  hiscore.dat is embedded in binary (precompile/hiscore_dat.h). External
+  hiscore.dat loadable via core option mame-external_hiscore from
+  system_dir/mame2010/. Cheats use per-game XML files (cheat.zip in
+  metadata/). Samples in system_dir/mame2010/samples/.
 
-  BIOS ZIPs are standard MAME romsets. The core looks for them in:
-    1. {content_dir}/ (same folder as the game ROM)
-    2. {system_dir}/mame2010/ (libretro system subfolder)
-    3. {system_dir}/ (libretro system root)
-
-  ROM naming follows MAME 0.139 conventions. ROMs from newer or older MAME
-  versions may not match expected CRC32/SHA1 values. Use a 0.139-specific
-  romset for full compatibility.
+  ROM naming follows MAME 0.139 conventions.

 notes: |
-  MAME 2016 is a libretro port of MAME 0.174, released mid-2016. Compared to
-  mame2010 (0.139), it adds 6 years of MAME development including significantly
-  better driver accuracy, ~9200 more ROM sets (23430 vs ~14000), and new hardware
-  support.
+  Frozen snapshot of MAME 0.174 (mid-2016). 69 BIOS root sets. Upstream
+  comparison (tag mame0174): BIOS root sets identical, romload.cpp unmodified,
+  no hiscore.c added. Shallowest libretro fork.
 
-  Key differences from mame2010 (0.139):
-    - Driver source files renamed from .c to .cpp
-    - Neo Geo: Universe BIOS updated to 3.2 (was 2.3 in 0.139)
-    - NAOMI: 23 BIOS variants (Japan/Export/USA/Korea/Dev), same EPR numbering
-    - Sega Lindbergh: new board support (lindbios.zip), 3 BIOS versions
-    - PGM2: new IGS PolyGame Master 2 support (no shared BIOS ZIP)
-    - Saturn driver split to separate saturn.cpp (was in stv.c)
-    - Dreamcast driver split to dccons.cpp, 5 BIOS variants
-    - PlayStation: expanded BIOS coverage (9 JP, 7 EU, 9 US variants)
-    - More Cave CV1000/SH3 games (26 sets, no shared BIOS)
-    - Model 2/3: improved emulation, same BIOS structure
+  Cheats use per-game XML files loaded from system_dir/mame2016/cheat/.
+  Samples in system_dir/mame2016/samples/.
+  Artwork in system_dir/mame2016/artwork/.
 
-  Key differences from current MAME (0.274+):
-    - Missing BIOS dumps added after 0.174 (newer redumps, alt regions)
-    - Neo Geo: no Universe BIOS 4.0 (added in later MAME)
-    - Some CRC32/SHA1 values differ for redumped ROMs
-    - Fewer Sega board BIOS region variants
-    - No Konami e-Amusement/Bemani expansions from post-2016
-
-  BIOS ZIPs are standard MAME romsets. The core looks for them in:
-    1. {content_dir}/ (same folder as the game ROM)
-    2. {system_dir}/mame2016/ (libretro system subfolder)
-    3. {system_dir}/ (libretro system root)
-
-  ROM naming follows MAME 0.174 conventions. Use a 0.174-specific romset for
-  full compatibility.
+  ROM naming follows MAME 0.174 conventions.
