KytyPlus v4.0 Release Notes

Overview

This release improves package installation and launcher support, and adds Minecraft (PPSA17221) to the compatibility table as Playable.

Package installation

• PS5 .pkg and PS4 fpkg support: The package installation flow now supports both PS5 packages and PS4 fake packages, so users can install either format through the emulator.
• .ffpfsc support in the GUI: The launcher now accepts .ffpfsc files for installation. Installed games appear in the game list, and the launcher supports double-click actions and right-click removal for these entries.

Minecraft compatibility

• Minecraft (PPSA17221) is now working in KytyPlus and is listed as Playable in the compatibility table.

Other changes

• Shader failure caching: Deterministic compute-shader compilation failures are cached, preventing the emulator from repeatedly recompiling the same failing shader.
• macOS build fix: Corrected an integer-type mismatch in package parsing that caused compilation to fail with Apple Clang.
