A fan-made native port of Gravity Rush Remastered that has reportedly been played through from start to finish on Windows, with sound and saves. It is worth a look if you already own the PS4 game and enjoy tinkering, but only NVIDIA GPUs have been tested so far.

The problem

Playing a PS4 title like Gravity Rush Remastered on a PC normally means an emulator: load the game, wait for shader compilation, and accept compatibility quirks. This project takes a different route. Instead of emulating the console, it loads the game's original x86-64 executable directly and supplies a runtime that replaces the PS4 system libraries, while the graphics go through shadPS4's Vulkan video core project overview. The user points the launcher at an unpacked game folder and presses Play, with the result being the game running as a Windows application rather than inside an emulator window.

What's different

The mechanism is the interesting part. The loader starts the original game code, a custom runtime implements the PS4 system functions it calls, and shadPS4's video core translates GPU commands and shaders to Vulkan shadPS4. The README says the runtime stops at the first PS4 function it has not implemented and names it, which makes missing behavior visible instead of a silent crash. On top of that, the port adds PC-side presentation options: render resolutions up to 4K, a 4096 shadow map, anisotropic filtering, FXAA/TAA, FSR 3.1 and DLSS with Native/DLAA, Quality, Balanced and Performance modes, while keeping the HUD as the game draws it.

The trade-off is that this relies on one particular game build. The resolution and shadow patches apply only to the European PS4 release CUSA01113, version 01.00, which the author tested. The project also builds on the technical approach of earlier native ports and the shadPS4 video core God of War port, MediEvil port, so its viability is tied to those upstream pieces and to the owner's ongoing work on the runtime.

Who should try it

This fits players who own the European PS4 disc or digital copy, have already unpacked it with their own tools, and want to see the game run on a Windows PC with modern upscaling. It also suits people interested in how native ports replace console system libraries, since the source is public and the loader reports unimplemented functions. It is a poor fit for anyone without a legally acquired copy, since the repository deliberately ships no game files, or for players on AMD or Intel GPUs looking for a tested path, as only NVIDIA cards have been tested so far. Prebuilt Windows zips are available from Releases, and setup is documented in Playing.

Requirements and limitations

The port needs 64-bit Windows 10 (1903 or newer) or Windows 11, and a GPU with Vulkan 1.3 and a current driver. The game must be supplied by the user as an unpacked folder containing eboot.bin, sce_module and sce_sys, prepared with the user's own tools; the tested configuration is the European CUSA01113 release at version 01.00. The launcher is unsigned, so Windows will warn on first launch, and the README tells users to proceed through the warning.

Trophies are not saved or shown, and performance and stability work remains on the roadmap; the author describes the release as version 0.1.8 with the whole story playable, and points bug reports at the issue tracker with screenshots and the run log issue tracker. Building from source is a separate path for developers, requiring MSYS2 with the CLANG64 shell, Python 3 with pillow and cryptography, and the package list in the packaging notes packaging instructions. Upkeep is ongoing: the launcher checks GitHub for new releases and installs them when the player agrees, keeping saves, settings and mods.

HotRepo's take

HotRepo first recorded the project on 2026-10-25, at 211 total stars and rank #25 on its NEW-REPOSITORY board for cpp; that is a snapshot of a new-project board, not a daily gain or overall Trending rank, and there is only one recorded date. With an eight-day-old repository and no comparable daily history, persistence of interest cannot be judged yet. Before investing time, check whether your copy matches the tested CUSA01113 version 01.00 and whether your GPU is NVIDIA, since both are documented boundaries rather than incidental notes.
