Sega's 1992 arcade game OutRunners as a native game for computers, the Nintendo Switch, Android and Anbernic's handhelds, built on its decompilation, outrunners-decomp: the game's program in C, checked frame by frame against MAME in picture and sound. Two games come out of it:

• OutRunners Arcade: the arcade game as it is, both cabinet screens side by side.
• OutRunners: the console version, the arcade game made for playing at home.

This repository contains no game data: you bring your own ROM set (MAME's orunners, World), and the game takes its assets out of it.

Download the package for Windows, Linux or macOS from the releases. Keep orunners.zip beside the game, or drop it on its window when it asks: the first time, it takes the assets out of it.

Each device has a package of its own: the game without its assets, and the tool (for Windows, macOS and Linux) that makes it on your computer with your ROM set:

• Nintendo Switch (outrunners-switch.zip): OutRunners NSP makes OutRunners.nsp, for a console with Atmosphere (ports/switch).
• Android (outrunners-android.zip): OutRunners APK makes OutRunners.apk (ports/android).
• Anbernic's H700 handhelds (outrunners-anbernic.zip, RG35XX, RG40XX...): OutRunners Anbernic makes the folder for PORTS (ports/anbernic).

What a tool makes has the game's data in it: it is yours alone, never share it.

• ARCADE: the arcade's game, one player.
• 2 PLAYERS: both seats in one race, side by side or one over the other.
• NETWORK: up to four devices on the local network (below).
• & KNUCKLES: CLASSIC (the arcade's game, a little more time), TIME ATTACK (against your fastest run's ghost), FULL (all 31 courses in one race), REVERSE (from a goal back to the start).
• OPTIONS: controls, difficulty, time, video (window, full screen, sharp, smooth or CRT pixels, a wider picture: 16:10 for a Steam Deck, 16:9 or 20:9; VSYNC), volume, sound test, steering, FPS.
• The pause in a race: CONTINUE, RESTART, QUIT GAME.

• Keyboard: the arrows steer, accelerate and brake; Q and A shift up and down; space is the radio; Enter starts and pauses.
• Game controller: the left stick or the d-pad steers, the right trigger accelerates, the left trigger brakes, the shoulders shift. OPTIONS > CONTROLS changes them.
• Racing wheel: a wheel SDL knows (a Logitech G29) works as it is plugged in. Any other (a Thrustmaster T300RS) is set up once in OPTIONS > STEERING > SET UP WHEEL: turn the wheel left, press the gas, the brake, and the buttons it asks for. Also in STEERING: WHEEL ROTATION (your wheel's range: 900 on a G29), CENTRING (the cabinet's spring, on a wheel with force feedback), VIBRATION (the cabinet's wheel shaking in a crash and off the road, or a controller's rumble) and INPUT TEST.
• Android: touch controls on the screen, or a controller. With the touch controls the phone itself vibrates in a crash and off the road, at VIBRATION's strength; STEERING > PHONE VIBRATION turns it off.

Up to four devices race together on the same local network (a house's Wi-Fi, or a phone's hotspot), as the arcade's linked cabinets: computers, phones and the Switch alike.

1. NETWORK > NAME: your name, as the rooms show it.
2. One device picks HOST.
3. The others pick JOIN, and the room.
4. The host's START starts a race of all of them; after it, back to the room.

A device that stops being heard holds the race a moment (WAIT); after 3 seconds the race goes on without it. If the one gone was the host, the next device hosts on. A firewall that asks about the game should let it reach the private network. The rooms and the race's datagrams are arcade-lan's, which the ports of other decompiled arcade games share.

• 4 PLAYERS on the Switch: up to four players in one race on one console.
• iOS and the New Nintendo 3DS: their ports, by yoshisuga, in pull request 14.

The game is free, and stays free. If you want to support the decompilations and the ports, there is Patreon, where supporters also have a say in what comes next, and GitHub Sponsors: entirely optional, nothing is locked behind either. If anyone asks you to pay for this game, it is not this project.

Python 3.10 or newer, CMake 3.20 or newer, a C11 / C++17 compiler and SDL2 2.30 or newer (on Windows its development package for Visual C++ unpacked in build/downloads/sdl2/; elsewhere the system's, libsdl2-dev on Debian and Ubuntu; or -DORUNNERS_STATIC_SDL2=ON to build it from its source). Clone it with its submodules and build it:

git clone --recursive https://github.com/cheviman/outrunners-port

cmake -S . -B build/cmake

cmake --build build/cmake --config Release

Both games land in build/bin/, and take their assets out of orunners.zip the first time (beside them, or in rom/). The devices' builds are in ports/switch/, ports/android/ and ports/anbernic/, each with its README; console/PLAN.md holds the console version's plan and what is done. The decompilation itself (its status, the tools, the assets' formats, the checks against MAME) is outrunners-decomp's README.
