# Namco 2x Systems: rebuilding System 21, 22 and 23 arcade games

> Namco 2x Systems rebuilds Namco System 21, 22, and 23 arcade games for Linux and Windows from MAME ROM sets, version 0.271 or later. The playable list includes Prop Cycle, Rave Racer, Tokyo Wars, Dirt Dash, Armadillo Racing, Time Crisis, Ace Driver, Cyber Commando, Ridge Racer 2, Cyber Sled, Time Crisis II, Crisis Zone, and Angler King. Each game names its zip, such as propcycl.zip or timecrs2.zip. Checksums are in docs/ROM_CHECKSUMS.md. The DSP BIOS is built in, so namcoc71.zip is not required.
