VBlank flag perhaps?
Well spotted on the dodgy single precision ops. I'd actually started to rewrite the x87 implementation when your patch came in (to support 80-bit precision, tag word updates and exception handling among other things) but it was good to have the fix in the meantime.
With my WIP x87 rewrite, I see this:
Kale and I suspect the bad textures are due to incorrect flash ROM loading. The game also needs flash ROM saving implemented for service mode to work correctly.
