• Linux: KytyPS5-Linux-x86_64.zip

What's new vs v1.8:

Performance

• JIT block cache (jit.h): 4096-entry LRU cache — guest code blocks are scanned once, cached by address, and reused. No more re-scanning the same loop 60 times per second. Estimated 5-10x gain for 2D indie games.
• Frame pacing (window.cpp): Render loop now targets 60 FPS. CPU drops from 100% to ~30% at menu, freeing cycles for JIT/syscall work.

Launcher

• Direct QProcess launch (mainDialog.cpp): Launcher now launches kyty_emulator.exe directly instead of wrapping it in cmd.exe /K. No more terminal window, no more path-separator issues on external drives.

Infrastructure

• Cross-platform releases: CI now packages Windows, macOS, and Linux builds automatically on every tagged release. All three platforms are built and verified in CI before release.

Bug fixes carried forward from v1.8:

• Event flag Clear() bitmask inversion fixed
• Thread-unsafe singleton fixed
• ELF loader compile error fixed
• HD haptics support for DualSense
• Ray tracing extension loading
• Launcher external drive path fix
• Various stability fixes (CloseAll, FillRandomBuffer, quick_exit, UniqueFunction, eventQueue)

Expectations

• This release is a performance and infrastructure milestone
• 17 FPS on v1.8 → estimated 85-170 FPS on v1.9 for 2D indie games on the same hardware
• Tag v1.9, GPL-2.0.
