etabeta78 218ea90606 (MESS) spc1000: converted the expansion bus EXT1 to be a 
slot device, moved FDD expansion to be a slot card, added
emulation of the VDP expansion as another slot card. This
makes Gun Fright, TwinBee and Zanac playable if you launch
them with "-ext1 vdp" option. If you want to emulate a
SPC-1000 with floppy drive, you have to add "-ext1 fdd"
instead. [Fabio Priuli]

out of whatsnew: disk emulation still does not work (unless we use
Meeso Kim's patched BIOS), but emulation is now closer to the real
functionality and we needed the changes for the VDP unit emulation.

nl_examples Preliminary support for LTE dynamic time-stepping based on Local truncation error. This enables the possibility to connect a capacitor between ground and a TTL output and get a e.g. 100 ns delay with a 1nF capacitor. 2014-05-15 22:50:40 +00:00

What is MAME?

MAME stands for Multiple Arcade Machine Emulator. When used in conjunction with an arcade game's data files (ROMs, CHDs, samples, etc.), MAME attempts to reproduce that game as faithfully as possible on a more modern general-purpose system. MAME can currently emulate many thousands of classic arcade video games from the the very earliest CPU-based systems to much more modern 3D platforms.

The ROM and CHD images that MAME requires are "dumped" from arcade games' original circuit-board ROM chips, hard disks, and CD-ROMs. MAME becomes the "hardware" for the games, taking the place of their original CPUs and support chips. Therefore, these games are NOT ports or rewrites, but the actual, original games that appeared in arcades, complete with all the bugs, glitches, slowdowns, and subtleties of the original game as it appeared in the arcade.

MAME's purpose is to preserve these decades of video-game history. As gaming technology continues to rush forward, MAME prevents these important "vintage" games from being lost and forgotten. This is achieved by documenting the hardware and how it functions. The source code to MAME serves as this documentation. The fact that the games are playable serves primarily to validate the accuracy of the documentation (how else can you prove that you have recreated the hardware faithfully)?
