DrZ80(snd) and Cyclone+DrZ80(snd) only replaced the Z80s flagged CPU_AUDIO_CPU, and many sound Z80s are not flagged (CPS2, Taito, Toaplan, the Mega Drive based boards...): those games kept the C Z80 with no sign in the log. Now, on a board with no flagged CPU whose first CPU is not a Z80, its first Z80 is taken as the sound CPU too, except where DrZ80 can't run it: a Z80 with a daisy chain (DrZ80 has none), the CPS1 QSound Z80 (Kabuki-encrypted opcodes) and the Tatsumi sound Z80 (Round Up 5 hangs). The log says which Z80s are replaced and which are kept. frontend_list.h: removed the entries that could do nothing, with the same result for every game: 82 names not in the core, 531 games with neither a 68000 nor a Z80, and a second zzyzzyx2 entry never reached.

What is MAME 2003-Plus?
MAME 2003-Plus (also referred to as MAME 2003+ and mame2003-plus) is a libretro arcade system emulator core with an emphasis on high performance and broad compatibility with mobile devices, single board computers, embedded systems, and similar platforms.
In order to take advantage of the performance and lower hardware requirements of an earlier MAME architecture, MAME 2003-Plus began with the MAME 2003 codebase which is itself derived from xmame 0.78. Upon that base, MAME 2003-Plus contributors have backported support for an additional 350 games, as well as other functionality not originally present in the underlying codebase.

See an incorrect entry? Create a new issue to let us know! This allows us to keep the compatibility table as accurate as possible by fixing it at the source.

Romsets and how to build them for this core
mame2003-plus was originally built from the MAME 0.78 codebase, meaning that 95% or more of MAME 0.78 romsets will work as-is in mame2003-plus, where they immediately benefit from its bugfixes and other improvements. In order to play the new games and games which received ROM updates in mame2003-plus, you will need to find or build the correct romsets.
