Avocado vs Gamma

Avocado is a free, open-source PlayStation 1 emulator for Windows, macOS, Linux, and Android. It can load files including .cue, .bin, .img, .chd, .ecm, .exe, .psexe, .psf, and .minipsf by drag and drop. Listed save tools include save states, quick save and load, and rewinding by one second. It supports digital controllers, DualShock, and mouse input, with up to two controllers and no multitap. Audio support includes XA-ADPCM and Red Book, and graphics use OpenGL hardware rendering. The project lists support for Anti-Modchip and LibCrypt protected games; PAL LibCrypt games need additional .SBI or .LSD subchannel information. A BIOS from a real console is required and must be placed in the data/bios directory; BIOS selection is prompted on first run. The project is in early development, so games may not start or may crash soon after. It is single-threaded, and audio synchronized to NTSC 60 Hz can stutter in PAL games.

Gamma is a PlayStation 1 emulator for iOS, iPadOS, and macOS. It supports touch and gamepad controls, save states, screenshots, game importing, and games that span multiple discs. For 3D games, the App Store listing describes enhanced resolution up to 8× and widescreen options. Supported disc images include BIN/CUE, CHD, PBP, ISO, and MDS; archive formats include 7zip, ZIP, RAR, and ECM. Cheat support and RetroAchievements are also listed. Optional Gamma Sync can connect Google Drive or Dropbox to store and retrieve selected emulator data. Games, BIOS files, memory cards, save states, and controller skins normally remain on the device unless a selected 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. It is free to download and use, though the free version may show advertising through Appodeal and its partners. Gamma Pro – Remove Ads is listed for $4.99.
