PPSSPP vs Snes9x

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.

Snes9x is freeware for playing most games made for the Super Nintendo and Super Famicom systems. Desktop builds are listed for Windows, Linux, and macOS, with additional libretro core builds for Android, Emscripten, Wii, Switch, GameCube, and PSP. Running games requires SNES ROM images. Snes9x can save game state to freeze files and game data to SRAM files. Windows documentation describes Game Genie and Pro-Action Replay cheat formats, a cheat search feature, and recording gameplay actions for later playback. Netplay is documented for as many as five players, but the project notes that it has not been maintained or tested in a long time and might be broken. The Unix documentation says the emulator does not reproduce exact sub-cycle timing between major system components, so games with strict timing needs may not run. The project lists the software as free, with a plan price of free. Its listed platforms include Android, Linux, macOS, and Windows.
