Syphon Filter 2 Recompilation
The original game's compiled code translated into a native program for a new platform, usually a PC port.
Based on Syphon Filter 2
Original game imageAbout
An experimental Windows static recompilation of the complete two-disc Syphon Filter 2 (USA) release, built with PSXRecomp. It runs the original retail game logic as a native x64 program over a PlayStation hardware runtime. The README states that this is a recompilation, not a decompilation, and that v0.1.3-alpha is not a finished PC port. Both discs and the connected campaign have been played and verified.
How it differs from the original
The launcher offers optional native 16:9, PGXP-assisted geometry and direct mouse camera control, all off by default, while retail gameplay, scripts, collision, saves, AI and the 20 Hz world update are kept. High refresh and 60 FPS are not supported.
Getting started
The download is an owned-input setup kit, not a prebuilt game. Extract it to a path without spaces, put your own Disc 1 CUE and BIN files beside it, then double-click the setup script, which downloads pinned tools, builds locally and opens the launcher. Later runs use the generated play script. WinGet, Git, pip and Visual Studio are not required.
History
Development was AI-assisted and human-directed, with acceptance based on deterministic routes, runtime telemetry and human visual testing.
Known issues & limitations
- The project is an alpha, not a finished PC port.
- Native 16:9 and PGXP are off by default; wider campaign coverage for 16:9 is wanted.
- Full campaign save/load coverage is still wanted.
- High-refresh or 60 FPS play is not currently available within the project without partial decompilation or an equivalent semantic world interface.
- Streamed overlays are interpreter-owned in this alpha, and true 60 FPS is judged unattainable without at least partial matching decompilation.
