Dojo Lobby is an online matchmaking platform for Flycast Dojo & Supermodel Dojo.

Just fill in your player details, point to your ROM directories, and select the games you want to play. From there, you can quickly filter and challenge active players from around the world.

Feedback and bug reports are appreciated on the Dojo Project Discord.

Reporting Bugs & Troubleshooting

This is a preview release, intended to test out basic functionality, initial matchmaking, and relay assignment. As such, there may be some rough edges to work out. As you provide bug reports, be sure to provide your platform details and relevant logs when available.

If you encounter connection issues, be sure to check the Relay Status and change your preferred relay server in your Network settings if you experience issues. You can also try having your opponent initiate a challenge so that the game will start on their own preferred relay server if they differ. Since relays are being tested in this round, server load may be high for the moment. Once relay functionality is assessed, we will move on to testing hole punching by default, with relays only used as a fallback.
