MAME's purpose is to preserve decades of software history. As electronic technology continues to rush forward, MAME prevents this important "vintage" software 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 software is usable serves primarily to validate the accuracy of the documentation (how else can you prove that you have recreated the hardware faithfully?). 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.

Raine (for Rainbow Islands Emulator) is an arcade multiemulator, it can handle games from CPS systems, Taito, Jaleco and it's run titles from NeoGeoCD (in last year project raine and neoraine was combined in one application).

SpeedVicio released another test version of the overlay MedGUI - a very convenient interface for multiemulator Mednafen , which in itself is not very friendly to setup. Reborn version of the application is completely modified compared to the normal MedGUI.

Nintendulator is an open source Win32 NES emulator written in C++. The original goal was to emulate the NES down to its hardware quirks; though it's fallen behind over the years, recent builds have caught up once again and can emulate certain behaviors most other emulators neglect to handle. However, this emulation precision comes at a price - a 1500MHz (estimated) or faster CPU is required to emulate at full speed. Supported file formats include .NES, UNIF, FDS (fwNES format), and NSF. Mappers are handled using external DLLs, complete with extra sound channels for most games which provide them. Other notable features include writing to FDS images (by storing the differences in separate files), Game Genie support (limited to 3 codes), customizeable controllers (including 4 player), input movie recording and playback (with re-recording), AVI Read more
