Erings

Accuracy

competition

Erings is a Sega Saturn emulator focused on playing the majority of officially licensed games while prioritizing usability over perfect hardware accuracy. It supports Windows, macOS, and Linux, with features including RetroAchievements, save states, rewind, 4MB RAM expansion, MPEG card support, rumble, NTSC/PAL regions, and HLE BIOS. Still a work in progress, it offers good compatibility while retaining some hardware and game compatibility limitations.
