Flycast vs PPSSPP

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.

PPSSPP is a PSP emulator for running games and other software made for the Sony PlayStation Portable. It is available on Android, iOS, Linux, macOS and Windows, with a free plan at free. Games can run at full HD resolution or higher, with texture upscaling and post-processing shaders. Players can use save states and a turbo button, customize touch controls, or connect a controller or keyboard. Save data transferred from a real PSP can continue a game. PPSSPP supports PSP ad hoc and infrastructure multiplayer, including ad hoc play through relay servers, and supports RetroAchievements after account sign-in. It runs PSP software only, not PS1 games or UMD Video discs; users must supply their own PSP game files. Compatibility reports are collected anonymously only when manually enabled. The open-source project is licensed under GPL 2.0 or later. Its official site provides documentation, FAQs, troubleshooting guides and community forums. PPSSPP Gold is available for Android, Windows, macOS and iOS, but not currently for Linux or Steam Deck.
