I tried to see if graphics can be ripped in MAME by using F4 and I was greeted by a black screen
To some who think "it's a 68000 12Mhz so a 68020 14Mhz can do it", but the 68000 only computes object positions and select tiles & x/y. The graphic tile engine converts 4 or 8 bytes of coordinates/tile/sprite info into 16x16 or 32x32 or whatever colorful graphics instantaneously. That's why console/arcade to computer conversions are so frustrating.
