[BUG]: SLUS-20937 Wild ARMs Alter Code F - GPU Palette Conversion broken in 2.2.0

[rbrettj]

Describe the Bug

I noticed once upgrading from 2.0.2 to 2.2.0 that Wild ARMs Alter Code F's rendering looked way different: textures would disappear or be replaced, triangles would completely disappear, etc. I started messing around with the settings and checked the Manual Hardware Renderer Fixes which seemed to resolve the issue. The display said that this changed gpuPaletteConversion = 2 (not sure how that aligns with a checkbox but okay).

That's the best I can give you at the moment. Not sure what could have caused it, but there appears to be a workaround, which is good.

Reproduction Steps

Enable or disable GPU Palette Conversion. I had to manually restart the game to see the broken state, as enabling it fixed it at runtime.
