HopStation vs WiiSX

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.
