mkpsxiso vs ScePSX

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.

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. Users can save and load progress, manage multiple save files, use cheats, edit and search memory, and play online multiplayer. Supported game image formats include .bin/.cue, .img/.cue, .iso, and .chd. The emulator supports D2D, D3D, OpenGL, and Vulkan renderers, which can be switched dynamically. Hardware backends support output up to 4K, while the software backend offers xBR and JINC upscaling. PGXP geometry enhancement works on 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 must provide one. Optional GameDB and ControllerDB downloads are listed, and the project accepts bug reports, suggestions, and contributions through GitHub.
