Flycast vs Flycast

Flycast is a free emulator for Sega Dreamcast, Naomi, Naomi 2, and Atomiswave. Its Android listing says it runs most Dreamcast games, including Windows CE titles, and arcade games for Naomi, Naomi 2, Atomiswave, and System SP. Graphics options include OpenGL and Vulkan, high-definition and widescreen play, and custom high-definition texture packs. The Android listing specifies 10 save-state slots and names RetroAchievements, modem and LAN adapter emulation, and Power Smash online support in update notes. The project offers regular master builds, experimental nightly development builds, and versioned stable releases. The builds page describes master as relatively stable and cautions that other branches may be unstable, crash, or fail to run. Flycast is available for Android, Linux, macOS, and Windows, with controller support and online multiplayer listed. Game files are not included and must be owned by the user. The repository identifies the license as GPL-2.0.

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.
