I fixed the problem by changing the M68000 speed from 12Mhz to 8Mhz in the CPS1.C driver file and recompiling mame. Works great. Speed is close to perfect when comparing to actual PCB. You can make it any speed you want, mame has a file (xtal.h) that has just about every frequency you can imagine to speed up or slow down the emulation of the M68000 chip. If you need help with the code or recompiling mame, let me know.
