In their own words
Gamma
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.
mkpsxiso
mkpsxiso builds PlayStation CD images from an XML document, with output in .bin/.cue or .iso formats for emulators or CD burning. File order in the XML sets LBA placement, which the project says can support access-time optimization. The builder handles mixed-mode CD-XA content, including XA audio and STR video, and CDDA tracks sourced from WAV, FLAC, PCM, or MP3 files. Its related tool, dumpsxiso, extracts PlayStation disc images and can generate compatible XML. It supports 2352-sector images and CUE files, and can extract tracks, license data, and raw sectors. Generated XML follows strict LBA order and preserves timestamps and XA attributes. The project targets homebrew development, ROM hacking, and reverse engineering. It runs on Linux, macOS, and Windows, and is GPL-2.0 licensed. Documentation covers command-line use, XML structure, track types, ordering, errors, and validation. Users supply their own Sony license data for injection. On ext4 and xfs, absent XML dates prevent 1:1 rebuilding for certain older files; Windows also has a documented directory-browsing issue with some nested structures.
