KytyPlus v3.4 Release Notes

Overview

v3.4 fixes a critical packaging bug where the shadPS4 backend wasn't bundled into the release, and hardens the game-loading path so real commercial content can actually boot. This release includes the first verified licensed-content boot on the shadPS4 delegation path.

Changes

🐛 Critical fix — shadPS4 backend bundled

• Fixed: shadPS4 backend was not included in the release, breaking the PS4 delegation path entirely. The shadPS4 runtime is now correctly bundled so PS4 titles can be dispatched and executed.
• Result: the PS4 delegation path is fully operational again and verified against real content..

Known Limitations

• "Install Package (.pkg)" may fail for some games — titles can be unrunnable from the .pkg install and must instead be extracted manually and loaded via eboot.bin. This includes licensed (signed) PS4 content — homebrew/unofficial packages install fine, but licensed titles generally require the extraction path. Root cause (installer/registration of signed packages) is under investigation.

Setting up your path

To run your legally obtained PS4 games:

1. Download and extract the release, then run launcher.exe.
2. Run your game through launcher.exe — on first run, shadPS4 should create its folder automatically (its data directory with a sys_modules subfolder).
3. Wait for that folder to appear, then place your legally dumped sys_modules files into the folder named sys_modules.
4. Load the game again through launcher.exe. If the .pkg install fails, use the extraction path: complete the game folder (including required sce_module PRX files) and load eboot.bin directly.

KytyPlus does not ship or download firmware, dumps, or sys_modules. Use only files you have obtained legally.

Thank you to all testers and contributors!
