Flycast vs mGBA

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.

mGBA is a free, open-source emulator for Game Boy Advance games, designed to run on lower-end hardware while maintaining accuracy and portability. It also emulates Game Boy and Game Boy Color; most GBA games boot, while the FAQ notes bugs in Game Boy and Game Boy Color support. Nintendo DS support is very early, limited to the medusa branch, and has poor compatibility. Desktop downloads cover Windows, macOS, Linux, and Ubuntu, with homebrew builds for Nintendo 3DS, Nintendo Switch, Wii, and PlayStation Vita. Supported GBA peripherals include rumble, rotation and tilt sensors, a solar sensor, realtime clock, partial link cable support, and BattleChip Gate. Game Boy features include rumble, tilt, realtime clock, Game Boy Printer, and partial Game Boy Camera and Super Game Boy support. The Wireless Adapter, IR Adapter, and Soul Adapter are not supported. Built-in Lua scripting can access emulator memory, registers, save states, buttons, game information, screenshots, callbacks, and frame or instruction advancement. The project began in April 2013 and uses the Mozilla Public License 2.0.
