All emulated game share the 'core' routines which handle things like 6809 emulation, sound generation, sprite and text drawing. The core program can support multiple games, the specifics of each game are handled by a custom 'driver' to emulate the particular hardware. The first release of the emulator was at the San Diego Classic Arcade party, have a look at some pictures from that event here Īfter getting the first version out, which were stand alone programs, I decided it'd be a good idea to merge them into one program. Over time, MAME (originally stood for Multiple Arcade Machine Emulator) absorbed the sister-project MESS (Multi Emulator Super System), so MAME now documents a wide variety of (mostly vintage) computers, video game consoles and calculators, in addition to the arcade video games that were its initial focus. MAME is a software that runs on a PC, Raspberry Pi or other hardware and emulates old arcade machine hardware in a software platform. I was looking for something else to do rather than actually complete PC*Bert. MAME originally stood for Multiple Arcade Machine Emulator, but lately they’ve just been calling the system MAME as a brand rather than an acronym. The emulator was coded over a period of about 6 weeks, during the months of May to June. Over time, MAME (originally stood for Multiple Arcade Machine Emulator) absorbed the sister-project MESS (Multi Emulator Super System), so MAME now documents a wide variety of (mostly vintage) computers, video game consoles and calculators, in. So after a little coding, and a lot of debuggering, the 6809 simulator lived, a few days after that 'hey presto' the Mappy emulator was born! Unlike the official Namco release, which when run on a Pentium Pro ( yes I overclock ) only manages 96% original game speed ( or only 31% if the screen is maximized ), mine achieves 100% speed of the original, even on an old Pentium 90 !! MAME is a multi-purpose emulation framework it's purpose is to preserve decades of software history. Having already learned 6809 assembly programming, through another project, I figured that writing a simulator in x86 assembler wouldn't be a big deal, well the 6809's hardly got any registers and only a small number of instructions ( I think it's like 79 total). I decided it was about time someone wrote a decent Namco emulation ( for purely educational uses by owners of the original game boards ). After seeing the PATHETIC effort Namco made in emulating Mappy for the PC, running under winslows'95 it was terrible.
