What ScePSX is
ScePSX is a free, MIT-licensed PlayStation 1 emulator written in C#. It runs on Windows, Linux, macOS, and Android; Android requires version 5.0 or later, with 9.0 or later recommended. It supports saving and loading progress at any time, multiple save files, cheat codes, memory editing and search, and online multiplayer. Supported disc-image formats include .bin/.cue, .img/.cue, .iso, and .chd. Users can switch among D2D, D3D, OpenGL, and Vulkan renderers. Hardware backends support output up to 4K, while the software backend offers xBR and JINC upscaling. PGXP geometry enhancement works across software and hardware backends and can be adjusted without restarting; ReShade effects work on D3D, OpenGL, and Vulkan. Controllers are described as plug-and-play, and keyboard bindings can be customized. ScePSX does not include BIOS files, so users need to provide one. Optional GameDB and ControllerDB downloads are available, and the project accepts bug reports, suggestions, and contributions through GitHub.

Who it suits
ScePSX suits players looking for a PS1 emulator on desktop or Android, especially those who want multiple graphics backends, save states, or online multiplayer. Android users need version 5.0 or later, and all users must provide a BIOS file.
Verdict
ScePSX combines several graphics options with save states, multiplayer, cheats, and memory tools. A BIOS file must be supplied separately, and users should account for the stated save-state incompatibility when using version 0.2.0.1.
