Open-source PlayStation 1 research
PSXRecompStudio
A development environment for PlayStation 1 (PS1 / PSX) binary analysis, MIPS R3000A analysis, static recompilation research, reverse engineering, and native porting experiments.
PSXRecompStudio focuses on building and validating the technical foundations needed for reliable PlayStation 1 recompilation. It does not yet recompile complete commercial PS1 games into native ports.
What works today
- R3000A / MIPS I instruction modeling, decoding, memory behavior, delay-slot behavior, exceptions, interrupts, and deterministic Golden Trace validation.
- Disc-analysis flow covering CHD input, ISO 9660 structures, PS-X EXE extraction, MIPS analysis, basic blocks, and control-flow graph extraction.
- A synthetic MIPS recompiler vertical slice: MIPS to IR lowering, host C generation, bounded execution, and differential validation against the interpreter.
- Compiler-enforced architecture boundaries and a stable C# to C++ interop boundary.
Not yet implemented
- End-to-end recompilation of complete commercial PlayStation 1 titles.
- A finished runtime for native PS1 game ports.
- Complete GPU, SPU, CD-ROM, MDEC, and GTE support.
- General real-ROM function recompilation integrated with the validated recompiler path.
Technology stack
Avalonia
Cross-platform desktop application shell and future analysis workflows.
C++ and CMake
Native CPU and hardware-oriented components built behind a stable C ABI.
C ABI and P/Invoke
A narrow managed/native boundary keeps C++ implementation details out of C#.
