HopStation vs QuackStation

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.

QuackStation is a free PlayStation 1 emulator with a Qt front end and a fullscreen interface for TV use. Its project goals include playability, speed, long-term maintainability, and performance suitable for low-end devices. It supports hardware rendering through D3D11, D3D12, OpenGL, Vulkan, and Metal, as well as software rendering. Hardware graphics options include upscaling, texture filtering, 24-bit true colour, and PGXP geometry precision and texture correction. Playback features include save states, runahead, rewind, fast boot, CPU overclocking, and time-stretched audio. Games can load from CDs and formats including BIN/CUE, raw BIN/IMG, MAME CHD, ECM, MDS/MDF, and unencrypted PBP. It supports digital and analog controllers, lightguns simulated with a mouse, NeGcon, and multitap for up to eight devices. A PS1 or PS2 BIOS ROM image is required and is not included; users must dump it from their own console. The project is licensed under GNU GPLv3 or later. Android is currently unmaintained and unsupported.
