This community is unofficial. Let me know if a developer of RetroAchievements wishes to have a Lemmy community.
RetroAchievements is a service that adds achievements to old games! From Gameboy to PlayStation 2 to the TurboGrafx-CD, regular and challenge achievement sets are available across myriad games and game hacks.
The achievement system is baked into specific emulators, and requires nothing more than the proper ROM or ISO and your user credentials to start earning.
SaGa Frontier? I'm replaying it and man, the satisfaction of finishing those character storylines or mastering the combo system with an achievement for it would be epic.
