About

Syphon Filter PC is an unofficial Windows PC runtime for the NTSC-U 1.1 release of Syphon Filter (SCUS-94240). It combines the original PlayStation gameplay code with a native Windows host for rendering, input, menus, audio and FMV playback.

How it differs from the original

It adds a launcher with Graphics and Controls tabs, a Dossiers gallery, configurable resolution, aspect mode, texture filtering and SMAA/MSAA, and an optional Russian text pack. The launcher interface is available in English and Russian.

Getting started

The repository contains no game or disc image; a BIN/CUE image of the USA v1.1 release is required. Download the Windows x64 zip from Releases, run syphon_filter.exe, browse to the CUE file and select Play, keeping every BIN file next to its CUE file.

Known issues & limitations

The project is still a public test.
Other regions, revisions, repacks, and modified images are not expected to work.
The launcher intentionally has no mission-selection or cheat controls.

What you need to run it

Original game files required. The project ships code only; you provide your own copy of the game (Windows version).

Only USA / NTSC-U, serial SCUS-94240, revision v1.1 in BIN/CUE format is supported.

Features

The complete 20-mission campaign supports checkpoint restores and persistent mission unlocks.
Graphics options include resolution, aspect mode, fullscreen, frame pacing, filtering, SMAA/MSAA, and optional volumetric effects.
An optional Russian text pack covers missions, menus, briefings, weapon descriptions, and map labels.
The project supports remappable keyboard and mouse controls plus retail-style gamepad controls.
Rendering supports high-resolution, perspective-correct, Z-buffered scenes and PGXP geometry.
The project restores the PS1-style HUD, inventory, objectives, weapons, and map pages, with position and objective indicators.

How to install

Extract the ZIP into a new folder, then run syphon_filter.exe.
In Launch, choose Browse and select the CUE file for the USA v1.1 game image; review Graphics and Controls, then select Play.
Keep every BIN file beside its CUE file and do not rename files referenced by the CUE sheet.
