In their own words
HopStation
HopStation is a work-in-progress PlayStation emulator written in C++, shared chiefly as a reference for emulator developers rather than as a primary way to play games. It emulates the R3000 CPU, GPU, DMA and interrupt controllers, CDROM, GTE, SPU, MDEC, and memory cards. The project provides a windowed application and a headless command-line mode, with tools including a disassembler, executable sideloading, USB controller input, configurable logging, a VRAM viewer, and ImGui introspection windows. It accepts BIN/CUE disc images, but support is buggy: CUE parsing prevents many games from loading, and inaccurate CDROM emulation also limits compatibility. The SPU lacks features such as volume sweep and dynamic ADSR. A PlayStation BIOS is required; only SCPH1001, the original US launch version, has been tested. HopStation builds for Windows, Linux, and macOS and is free under the MIT License. Some builds need additional shader libraries. The author describes it as an unfinished personal learning project and says feature contributions are unlikely to be accepted.
ScePSX
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.
