MAME stands for Multiple Arcade Machine Emulator is a reference to the inner workings of the emulated arcade machines. This is done both for educational purposes and for preservation purposes, in order to prevent many historical games from disappearing forever once the hardware they run on stops working. In order to preserve the games and demonstrate that the emulated behavior matches the original, you must also be able to actually play the games. To operate, the emulator requires images of the original ROMs, CDs, or hard disks from the arcade machines, which must be provided by the user.The Gaelco spree continues with Glass, Alligator Hunt and Maniac Square, and we’ve added support for two games on the hilariously misguided Tiger R-Zone system: Batman Forever and Indy 500. Emulation has been greatly improved for Mazer Blazer, Great Guns, and the Tecmo World Cup ’94 family of games, although all these games still have issues with unemulated protection.In computer emulation, we’ve added support for ZX Spectrum slot devices. You’ll still get the Kempston Joystick Interface by default, but you can now swap it out for other devices, including a number of Currah cartridges. There are also some big improvements to the HP9000/300 series, and support for HP85 option ROMs.
