DARAKU TENSHI - The Fallen Angels

I have this great game (at least in graphics) Daraku Tenshi,but it moves sooo slow...is it a problem related to the emu (mame PLUS!)...or I must "play" with some settings?
Do you know any other emu that plays this game ?

Thanks guys,you rule.

As usual heavily depends on your PC hardware, mostly CPU and RAM. I can run it here around 180% unthrottled (F10), you can check my PC specs on my profile. I'd try to disable auto frame skip and RDTSC timing system. Mame32Plus! probably has the best perfomance of any MAME build, but you might give a try to Mame32fx for example. I believe no emulator besides MAME run this game. Please note that the Hitachi SH-2 main CPU requires pretty CPU power

OK...I got it working perfect,except the sound (sometimes it's making an echo).
I know that is mostly from not having V-Sync,Tripple Buffer enabled.
Any other options?

Well, disabling Triple Buffer and specially V-Sync might hit the performance for good, but should not unsync the sound anyway. I'll tell you if I find another posible speedup, probably play a bit with over/underclocking the emulated CPUs
