Gamma

Gamma is a PlayStation 1 emulator for iOS, iPadOS, and macOS, with touch and gamepad controls, save states, screenshots, game importing, and support for multiple-disc games. The App Store listing describes enhanced resolution up to 8× and widescreen options for 3D games. Gamma supports disc images in CUE+BIN, CHD, PBP, ISO, and MDS formats, plus 7zip, ZIP, RAR, and ECM archives. Optional Gamma Sync can use Google Drive or Dropbox to store and retrieve selected emulator data. Games, BIOS files, memory cards, save states, and controller skins ordinarily stay on the device unless a feature transmits them, such as Sync or a community submission. Gamma does not include commercial PlayStation games or proprietary PlayStation BIOS files, so users are responsible for using content they have a legal right to use. The app is free to download and use, and the free version may show ads through Appodeal and its partners. Gamma Pro – Remove Ads is listed for $4.99.
