The arcade cabinet is really a Windows PC that believes two controllers are connected to it. Therefore, any Windows game with the right controller support is theoretically runnable on the arcade. The controller layout of the arcade is most similar to an Xbox controller, with the following buttons supported: A, B, X, Y, L1, L2, R1, R2, Select and Start. The stick is not analog and only sends directional inputs, so developers should not use sticks for their games and instead use D-Pad. For two players games, develop as if you're targeting two connected controllers.
In terms of displaying on the game selection list, developers should submit the following:
Title
All contributors
A short summary (2-3 sentences) of the game
Cover art of the game (itch.io cover art resolution preferred)
If your game meets all of these criteria, reach out to an officer (currently Gavin) to let them know and get them the build & info listed above!
