As of MAME 0.188, different Killer Instinct boot ROMs are no longer treated as different machines. They're now treated as different BIOS versions for a single machine.

MAME 0.188 MAME 0.188 comes to you with tales of perseverance, blind luck, and the kind of insanity you’d get from no-one else. By sheer chance, a DECO Cassette system Brian Troha picked up cheap happened to come with a set of graphics ROMs for Explorer. While the Explorer program cassette was dump...

MAME 0.187 And now for something completely different: our midyear MAME release. The most notable new working machines are beloved Game & Watch titles Donkey Kong Jr. (new wide screen) and Mario Bros., and the ultra-rare Kaneko prototype Jump Kun (thanks ShouTime). There are also some newly sup...

MAME 0.186 It’s been one of those long, five-week development cycles, but it’s finally time for your monthly MAME fix.

MAME 0.185 Today’s the day for our April MAME release, bringing some important fixes as well as the usual assortment of emulation improvements.

There aren’t a huge number of new working machines in this release, but there are some significant improvements. Thanks to kazblox, MAME now emulates some...

MAME 0.183 Hi everyone! It’s been a busy month for MAME development, and we’ve got a whole lot of surprises to unwrap today as we continue to celebrate twenty years of MAME. First up, we’ve added some incredibly rare systems to MAME. Omega is an Arkanoid-inspired arcade game with a production run o...

ShouTime dumped the incredibly rare game Omega (Nihon System) . It’s a ball-and-paddle game running on similar hardware to Sega’s Gigas. These games use an NEC MC-8123 CPU module containing a Z80 core, decryption circuitry, and an 8 KiB encryption key in battery-backed RAM. When fetching a byte from...
