PCSX-Redux Git (2026/10/09) is compiled. This is yet another fork of the Playstation Emulator, PCSX. While the work here is very much in progress, the goal is roughly the following: Bring the codebase to more up to date code standards. Get rid of the plugin system and create a single monolithic codebase that handles all aspects of the playstation emulation. Write everything on top of SDL/OpenGL3+/ImGui for portability and readability. Improve the debugging experience. Improve the rendering experience.
