Phase 2.1/5 of the Sega VDP / segac2.c clean-up: the Mega Play BIOS, memory maps, inputs, machine driver, NVRAM, ROMs and game drivers move from drivers/segac2.c to drivers/megaplay.c. The Mega Drive part (68000, sound Z80, I/O chip, interrupts, sound interfaces, pads) stays shared with the other Mega Drive based boards and is declared in includes/segac2.h; the Mega Play interrupt acknowledge is enabled through genesis_enable_iack(). - Set names as in current MAME: mp_twc is now mp_twcup, the BIOS version 2 ROM is epr-a15294.ic2; new clone mp_gaxe2a (Golden Axe II, original revision), as in MAME. - The Mega Play save state registrations move with the BIOS; the unused BIOS variables (bios_game, bios_6204, bios_6402) are removed. - Metadata: driver.c, mame2003-plus.xml (Mega Play entries regenerated), catver.ini, history.dat, CHANGELOG.md.

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.

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.
