RetroAchievements vs SteamVault

RetroAchievements adds achievement goals and progress tracking to retro games. Players can build profiles, follow completion, and compete with friends. Its game listings span systems from Atari 2600 to PlayStation 2 and include Nintendo, Sega, Sony, and other platforms. Supported emulator options include PCSX2, Dolphin, PPSSPP, Flycast, and BizHawk, with choices for Windows, Linux, macOS, Android, iOS, and browser-based SkyEmu.

Hardcore mode disables save-state loading, cheats, and most speed-altering emulator features. It is required for game mastery and some leaderboards. Community events include RA Roulette and Achievement of the Week, and developers can use public API documentation. Players can report broken achievements and request manual unlocks by providing proof of completion. The service is free. Its web application source code is GPL-3, while achievement trigger logic is proprietary to the RetroAchievements community. The service does not host copyright-protected ROMs. A player must be connected to the internet when starting a session, so fully offline play is not supported. System support and new features depend on volunteers.
