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.
