Links, repository & details

About

The README lists each as playable on Linux and Windows, with Rave Racer offering online play for up to 8 players. Each game's original program was taken apart with Ghidra and checked against the arcade machine running in MAME, and some programs are translated to C by a tool of the project.

How it differs from the original

The README lists widescreen support for Tokyo Wars, Dirt Dash and Time Crisis, and says the mouse acts as the gun in Time Crisis, with light guns also supported. It notes Time Crisis has not yet been compared with MAME frame by frame or note by note, so small differences are expected.

Getting started

You need your own copy of each game's files (the MAME ROM sets, from MAME 0.271 or later); they are not included.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Arcade version).

You need your own MAME game files; they are not included. Supported ROM sets are from MAME 0.271 or later.
Prop Cycle needs `propcycl.zip`.
Rave Racer needs `raverace.zip` and `namcoc74.zip`.
Tokyo Wars needs `tokyowar.zip`.

Features

A game controller works in all the games.
The menu can be opened with R3 or by holding Start for a second when using a game pad or Steam Deck.

How to install

Download a ready-made package from the Releases page; packages do not include game files.
On Steam Deck, put ROM zips in `~/.local/share/namco22/<game>/roms/`, add the game's AppImage to Steam from Desktop Mode, then start it in Game Mode.
On Windows, unzip the package, put the game zips in its `roms` folder, and double-click the game's executable.
