Summary	02788: jjack, dorunrun and clones: Immense emulation speed drop
Description	While other games in the driver stayed about the same execution speed, jjack and dorunrun now execute over 5 times slower than before. My run on XP1800: d:\emulator\arcade\mame>mame128u3 dorunrun -str 10 -nothrottle Average speed: 265.66% (9 seconds) d:\emulator\arcade\mame>mame128u4 dorunrun -str 10 -nothrottle Average speed: 47.15% (9 seconds)
