Summary 03592: outrun, outrunra, outruno, outrundx, outrunb: Master clock is incorrect
Description Main crystal on cpu board is 40mhz for Outrun, not the 50mhz used on Sega's Y-Board games (MAME has those correct). The dual 68000s should therefore probably be clocked at 10mhz for Outrun instead of 12.5mhz.
