Project Summary
MESS is a MAME-based project which documents the hardware for a wide variety of (mostly vintage) computers, video game consoles, and calculators through software emulation, as MAME does for arcade games. As a nice side effect to this documentation, MESS allows software and games for these hardware platforms to be run on modern PCs.
The goal of MESS is total accuracy to the original hardware behaviour, which is achieved through low-level emulation of all hardware components (video chips, CPUs, etc.), the implementations of which are shared across all emulated systems using the generic MAME architecture.
