And yet there are plenty of original games that run without problem on 
the SuperCPU.

Of the 3 c64 game  projects I have in the pipeline, 2 of them work fine 
while the 3rd suffers badly from running too fast. I'd not tried them 
until now, I somehow missed vice supporting it.

I can put in some frame limiting but the scrolling will still flicker 
due to the cpu being able to accelerate past the vic. This will take 
further consideration as having the faster cpu is actually useful, if I 
leave it running at 20mhz then I don't know how tollerant I can be for 
the cpu running faster due to the timing differences of ultimax mode.

Although I don't know how accurate vice is at SuperCPU timing either.
