CGX4 installed and problems found.. CGX4 uses CPU to VRAM blit operations that wasn't fully hooked up to Cirrus Logic emulation.

Now it really does work, at least 640x480x8. There is graphics corruption too (background isn't always erased), something to do with blitter emulation.

Picasso II/Picasso II+/Piccolo/Spectrum (both ZII and ZIII) now works in CGX4 mode. Piccolo isn't detected, probably something wrong in autoconfig data.

JIT seems to cause crashes, do not enable it.

EDIT: graphics corruption fixed. Yet another buggy "is blit valid" test..

EDIT2: Piccolo SD64 now works partially. Some modes only work.
