SpartanPort

English | Português (Brasil) | Español

SpartanPort is an unofficial PC port of God of War III Remastered (PlayStation 4) for Windows 10/11 and Linux (experimental AppImage).

No game files are included. You need a dump from your own PS4 (tested: CUSA01623 and CUSA01715, versions 01.00 and 01.02). This project is not affiliated with or endorsed by Sony Interactive Entertainment or Santa Monica Studio. God of War is a trademark of Sony Interactive Entertainment.

Formerly gow3_pc. Updating from 2.5.0 through the launcher keeps your saves and settings: on the first start, the game settings (gow3.ini), the launcher settings and, on Linux, the data folder (~/.local/share/gow3) are copied to their new names. The old files stay where they were, and existing shortcuts keep working. On Linux, the AppImage is now spartanport-x86_64.AppImage: update Steam launch options that use the old file name.

Download and play

• Windows 10 (1903 or newer) or Windows 11, 64-bit.
• A 64-bit processor with AVX: Intel Sandy Bridge (2011) or newer, AMD FX or newer. On CPUs without MOVBE, BMI1 or LZCNT (Sandy/Ivy Bridge, AMD FX) the loader rewrites the game's instructions that use them to emulated stubs and logs an ISA: line; performance on those CPUs has not been measured yet. Older CPUs stop at start with a STOP: this CPU lacks line in the log.
• A graphics card with Vulkan 1.3 and a current driver.
• Your copy of the game (the folder with eboot.bin, sce_module and sce_sys). Tested: CUSA01623 and CUSA01715, versions 01.00 and 01.02.

Steps

1. Download spartanport-windows.zip from the Releases page.
2. Extract it to a folder of your choice, for example C:\Games\spartanport-windows. Do not run it from inside the zip.
3. Open SpartanPort.exe. If Windows shows "Windows protected your PC", click More info, then Run anyway: the program is not digitally signed.
4. Click Choose the game folder. It takes you to the Game page. Next to Game folder, click Browse… and select the folder with eboot.bin.
5. Back on Home, the cover art and "CUSA01623 · version 01.02" appear. Adjust Quick settings if you like: display mode, frame rate limit, render resolution and engine frame rate.
6. Click Save to keep pending changes, then PLAY. The first start prepares the game image; shader compilation can also affect startup and performance on later launches.

Patches and fixes are included and applied automatically: texture fix, skip videos with X and 120 FPS are on by default. Change the resolution and frame rate on Home or Performance. The startup black-screen fix is always requested, even with an older saved patch selection; patches apply only where their signatures match. A resolution patch replaces the texture fix.

While playing

• Insert on the keyboard, or R3 + L2 on the controller, opens the port's menu: cheats, multipliers, image, performance and the performance overlay.
• Saved shaders load in the background. A small "Loading shader cache" note in the corner shows the progress.

Next time

• Play SpartanPort.exe starts the game straight away with your saved settings. You can make a desktop shortcut to it, or add it to Steam with Add a Non-Steam Game.
• Your saves, shader cache and log are in the user folder next to SpartanPort.exe. Keep that folder when you update.
• Advanced → Check for updates downloads and installs a new version. Your saves and settings are kept.

Linux (AppImage, experimental)

The Linux build runs the same native runtime and the same launcher. It was tested on Arch Linux with a Radeon RX 7800 XT (RADV) in a Wayland session.

You need: x86-64 Linux with glibc 2.39 or newer, an AVX-capable CPU, a Vulkan 1.3 driver and your own game dump. Launcher startup is checked on Ubuntu 24.04, Debian 13, Fedora 42, Arch and openSUSE Tumbleweed; this does not establish gameplay compatibility on every GPU.

Download and run

1. Download spartanport-x86_64.AppImage from the Releases page.
2. In its folder, run:

   chmod +x spartanport-x86_64.AppImage
   ./spartanport-x86_64.AppImage
   

3. Choose your game folder, save the settings and press PLAY.
