As I checked the video, it would also appear the maincpu also is higher than it needs be, probably by the same 50% (half) of current speed in MAME (at least for Speed Attack).

Yes, CPU clock is 50% speed of the gameplay is almost the same.
But the title demo is still fast.
From the speed difference in the test pattern at boot, it appears that writing to VRAM is slower?
