Played fine for me. Make sure you have auto frameskip enabled (useful for slower computers). so that the emulation does not dip below 100%. I'll leave this open for a bit for someone else to comment on their test of this game. |

can't confirm, the game has higher requirements than ancient versions due to it needing to run at perfect interleave level, however, it's still 290% speed on my machine, and I'm not seeing any actual game slowdowns even at 100%. |

The slow down is since MAME 0.128u4. MDRV_INTERLEAVE(100) was changed to MDRV_INTERLEAVE(10000). And later in 0.128u7 to MDRV_QUANTUM_TIME(HZ(600000)). If you now delete line 1832 in src\drivers\tnzs.c from MCFG_QUANTUM_PERFECT_CPU("maincpu") to //MCFG_QUANTUM_PERFECT_CPU("maincpu") you get the full speed again! |

and break the game in places. it's set to full interleave for a reason. 300% speed on a modern system is more than plenty. |
