Fix some glitch

[Naimbd69]

Hi Coder 787,

You did a great job creating Kyty Plus! I have an Intel Arc A580 GPU, and the current version of the Kyty emulator doesn't seem to support my GPU properly. I'm experiencing a fragmented shader error.

I tried your Kyty Plus version 3.8, and it works perfectly on my GPU. However, the newer versions of Kyty Plus don't work properly with my GPU. I've also installed the latest graphics drivers, but the issue persists.

Could you please look into this problem and try to fix it? I would really appreciate your help. Thank you for your amazing work on Kyty Plus!

Hi Naimbd69,

Thanks for the kind words, I really appreciated them.

I looked into the issue you raised in #15, and I made a v4.2 change aimed at the shader-output path you mentioned. The short version is that layer-export shaders now use the core ShaderLayer capability instead of the legacy SPV_EXT_shader_viewport_index_layer extension, and layer shaders now use SPIR-V 1.5 with the full entry-point interface. I also added a regression check for that path.

That said, this is not a 100% confirmed fix and still requires testing. The change is plausible, but I want real testing on the reported setup before calling it resolved. If you can retest with validation enabled and share the actual error log, Vulkan message, or crash details, that would help a lot.

I'm not trying to claim the bug is closed here. If it still fails, the next step is to narrow it down with the actual error output rather than guessing from the GPU model alone.

Hi Naimbd69,

Thanks for sharing the log. It shows the en dash in the game’s folder name was misread, so the emulator couldn’t open eboot.bin. KytyPlus v4.3 includes a Windows Unicode-path fix for this.

Could you please try the v4.3 build with the same game folder and let me know whether it gets past loading? If it still fails, please share the new log so I can investigate further. I can’t confirm the issue is resolved until it’s tested on your setup.
