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 $4.99.
no$psx
no$psx is freeware for Windows that emulates and debugs PlayStation 1 and PSone software. It is intended to run without special video drivers, plug-ins, virtual CD-ROM drives, a system BIOS, or per-game configuration. Supported disc images include CCD+IMG, CDI, CUE+BIN, MDS+MDF, CHD, NRG, and ISO, alongside raw EXE files and ECM/CDZ decompression. Real CD-ROM drives require wnaspi32.dll, with the maker noting problems on Windows NT/2000 and later. Development tools include a disassembler, debugger, profiler, code and memory breakpoints, assembler, I/O map viewer, VRAM viewer, polygon viewer, TTY console, and PSX hardware specifications. The free BIOS clone may have compatibility issues; an original PSX-BIOS.ROM can be placed in the program folder. The maker says many games have not been tested and compatibility problems may occur. The listed v2.3 Windows 32-bit release adds pixel-accurate GPU rendering, texture/CLUT cache emulation, and timing reproduction. The plan price is free.
