PCSX-Redux vs WiiSX

PCSX-Redux is a free collection of tools, research, hardware design, and libraries for PlayStation 1 development and reverse engineering, centered on a fork of the PCSX emulator. The project aims to replace the plugin system with a monolithic codebase using OpenGL3+ and ImGui. Debugging features include VRAM, MIPS, and SPU debuggers, save states, and a GDB server for controlling program execution from a compatible IDE. Users can also work with a Lua console and editor or connect to Ghidra 10.3 or newer for MIPS debugging and reverse engineering. Graphics options include software and OpenGL GPUs, filtering, true-colour rendering, MSAA, and wireframe or vertex polygon views. It supports Xbox controllers, digital and analog controller emulation, and PlayStation Mouse emulation. OpenBIOS provides a MIPS R3000A BIOS implementation that can boot games without a retail BIOS, although the listed system requirement says a BIOS is required. Downloads are listed for Windows Intel 64-bit, Linux Intel 64-bit AppImage, and macOS Arm. The project describes the codebase as usable but still needing cleanup before a first stable release, with experimental components.
