What it is
Flycast Dojo is a free, open-source fork of the Flycast emulator for Sega Dreamcast, Naomi, Naomi 2 and Atomiswave. Its focus is netplay and replay, with training tools for supported games. Players can connect using Match Codes, direct IP connections or virtual LANs such as ZeroTier or Radmin. Match Codes use an internet relay to help start peer-to-peer sessions through firewalls without an account or extra software. Netplay sessions can be recorded and played back, or transmitted to a replay server or listening spectator. Training Mode supports RetroArch .cht cheats, savestates, and recording and playing back inputs. Players can compare ROM MD5 checksums, while successful peer-to-peer play requires matching ROM and BIOS files. The project is bundled with Fightcade and Arkadyzja. It is listed for Android, Linux, macOS and Windows, though the official site links downloads for Windows, Linux and Mac. The documentation notes that Match Codes may have problems on some cloud gaming services or corporate networks.
