Technical notes

Frozen snapshot of MAME/MESS 0.159 (version.c says 0.159, core reports 0.160). Built from same repo as mame2015/ume2015/cdi2015 with TARGET=mess. 619 machine drivers (home computers, consoles, handhelds, calculators). No BIOS root sets (no GAME_IS_BIOS_ROOT in src/mess/). Machine ROMs loaded per-machine via MAME ROM system from content directory.

Software list support via 375 XML hash files in system_dir/mess2015/hash/. Hash files are bundled in the source repo at /hash/. Not on libretro buildbot. .info incorrectly says SYSTEMDIR\ume\hash — actual path is mess2015/hash.

hiscore.c integrated (libretro addition, not in upstream MAME 0.159). SAMPLES sound driver disabled in mess.mak. Per-game cheat XMLs via system_dir/mess2015/cheat/. Artwork layouts via system_dir/mess2015/artwork/.

Upstream comparison (tag mame0160): romload.c and softlist.c unmodified.
