Tuning model-2 tgp makes vf2 and dynamcop works, but frozen/crashes daytona...

While analyzing some model-2/2a non-working games, it seems some timing issues between copro tgp and i960 cpu prevented vf2 and dynamcop from running.

Tried tuning up tgp copro's clock to some particular value, vf2 and dynamcop will run much further.

However, daytona seems very "tgp clock sensitive". Even 2MHz overclock will either frozen the whole mame emulation, or crash it "segment fault" if running in debug mode.

If carefully running debug mode with single vblank, it can be caught at about 160+ frames, happens just when 3D demo starts.

Another, the frozen only happens with daytona, other clones such as daytona93, daytonase are working well.
