Gundam Code Fairy PS4RT for Windows is DiamondDogz’s Windows build of Gundam Code Fairy PS4RT, HekamiAeon’s runtime that runs the PS4’s Mobile Suit Gundam Battle Operation Code Fairy from the game’s own x86-64 code with a Vulkan renderer derived from shadPS4. The runtime is HekamiAeon’s work and the credit for it stays there; the Linux original is listed here as Gundam Code Fairy PS4RT. This build is the runtime’s version 1.0 with the changes Windows needed to start it.
It adds Sieg Zeon, a launcher in English and French that sets up the game folder, installs the update and the three volume key packages, and holds the same graphics settings as the in-game menu. The publisher’s screenshots show FSR 4 at 60 frames a second, and the runtime works with DiamondDogz’s Crowbar, which can start it and records the trophies the game unlocks.
It is a pre-release: it starts the game and plays it, but needs more testing before a stable version. No game files, keys or firmware are included. The publisher says about 90% of the Windows code was written with Grok, and the rest with Claude.
How to Set It Up
- Download the zip and extract the whole folder.
- Run
SiegZeon.exe. It isn’t code-signed, so Windows may warn: choose More info, then Run anyway. - Open Folders and choose the game folder, the update PKG if your game is 01.00, and the folder holding the three volume key PKGs. The launcher installs the update and keys itself.
- Press play. In the game, Insert, or L2 and R3, opens the settings menu.
