Gamma vs Vita3K

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.

Vita3K is a free, experimental, open-source emulator for PlayStation Vita, with builds listed for Windows, macOS, Linux, and Android. The project describes itself as hobby-driven, with developers deciding what to work on and when. Game compatibility varies: the FAQ says over 50% of tested games are marked playable, but not every title is supported and flawless play is not assured. Vita3K accepts .pkg, VCI, NoNpDrm, FAGDec, and manually decrypted games; Vitamin dumps are unsupported and Maidump is unstable. Some titles require PS Vita system modules installed with firmware packages. Keyboard and mouse work out of the box, and SDL3-compatible controllers are supported, with DualShock 4 and DualSense recommended. Vulkan is recommended when supported, while OpenGL remains available for older hardware. Ad-Hoc multiplayer is partly implemented and works with some commercial games through services such as ZeroTier or Tailscale. Users must dump their own commercial games; the project says it does not condone piracy. Minimum PC requirements include a 64-bit CPU, graphics capable of OpenGL 4.4 or Vulkan 1.0, and at least 4 GB RAM.
