Technical notes

SUBTARGET=mess build from libretro/mame. Same source, same CORE_NAME ("mame"), same paths (system_dir/mame/) as the mame core. Excludes arcade drivers, includes only console/computer/non-arcade drivers (~1290 driver files via mess.flt). 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. Hash directory contains software list XMLs needed for MESS software loading.

mess.flt exceptions: adds AES (+aes), CD-i consoles (+cdimono1, +cdimono2, +cdi910, +cdi490a), Atari Jaguar (+jaguar, +jaguarcd), CPS Changer (+wofch, +sfzch, +sfach, +sfzbch). Removes arcade 3DO machines (-3dobios, -alg3do, -orbatak, -md23do, -sht3do).

1 active IS_BIOS_ROOT (miuchiz). XaviX TV game parent machines serve as console BIOS for cartridge-based software (IS_BIOS_ROOT commented out in source but functionally required).
