bsnes vs Flycast

bsnes is a free, open-source emulator for Super Nintendo and Super Famicom games, with support for Super Game Boy and Satellaview. It runs on Linux, macOS, and Windows. Graphics options include HD Mode 7 with optional supersampling, a multi-threaded PPU renderer, and OpenGL multi-pass pixel shaders. The emulator also provides low-level emulation for SNES coprocessors such as DSP-n, ST-01n, and Cx4. It accepts standard ROM files, optional higan game folders, and 7-zip decompression, and can apply BPS and IPS soft patches. Its games database has thousands of entries, and its cheat database covers hundreds of popular games. Save states can include screenshot previews and names, with undo and redo. Other tools include rewind, frame advance, cheat code search, movie recording and playback, and screenshots. Speed settings are 50%, 75%, 100%, 150%, and 200%, with smooth audio output retained. The project lists nightly builds for Windows, macOS, Linux, and FreeBSD.

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.
