God of War 3 Launcher for Xbox

God of War III Remastered on the Xbox Series X|S in Developer Mode (not the Xbox One). This fork of SpartanPort, the PC port by Felipe Prado and its contributors, adds the Xbox app (xbox/); everything about the port itself is in SpartanPort's README.

No game files are included. You need a dump of God of War III Remastered from your own PS4 (tested: CUSA01715). 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.

Install

1. Download the zip from Releases and unzip it on a PC.
2. Device Portal → Add → the .appx and the package in Dependencies. If Dev Home lists the app as an App, set its type to Game.
3. Copy your dump (the folder with eboot.bin, sce_module, sce_sys and dvdroot_ps4) to one of:
   • a USB drive, in any folder. The app looks in \dumps\GodOfWar3 by itself and otherwise asks you to choose the folder once.
   • the console's internal storage, anywhere under D:\DevelopmentFiles (for example D:\DevelopmentFiles\dumps\GodOfWar3). The app finds it there by itself, up to three folders deep. This is the Dev Mode folder that apps may read; other places on the internal storage are closed to apps.
4. Start God of War 3 Launcher: Prepare (once), Precompile shaders (once, recommended), then Start game. The menu shows the game folder it uses; Choose game folder lists the dumps the app found (internal storage and USB) and can browse a USB drive.
   • Start game first loads every shader the game has used so far ("Loading shader cache"). This takes longer the further you play (about 3 minutes with 7,000 shaders), but then nothing has to be built during play.
   • Start game without loading shaders starts at once and builds each shader the first time the game needs it. After loading a save or entering a new area, some objects can appear a moment late.

In the game, RS + LT (click the right stick while holding the left trigger) opens the menu: render resolution (720p by default), overlay, Automatic QTE, vibration and more.

New versions install over earlier ones and keep your saves and settings.

Known issues

• 4K needs more memory than the Xbox allows. In Developer Mode an app gets at most 5 GiB. At 4K the app moves about 450 MiB of the game's memory to disk and runs at about 45 fps; heavy scenes can stutter or run out of memory. At 720p (the default) nothing goes to disk.
• Occasional ghosting. Now and then moving parts of the picture leave strong trails, for example during the opening camera move on Gaia's back. It doesn't happen on every start; it seems to come with frame rate drops, and its cause isn't known yet.
