Carnevil Accelerated

[mitsurugi]

Hello. I'm using groovymame 0.149 and carnevil game is accelerated. What can i do? manually edit the game?
thanks.

First find the reason why it's accelerated. You usually create a log to find this information.

Sorry for don't add the log file. I was reading it, but don't understand were is the problem. Maybe it sync a bad resolution...

[Calamity]

No problem mitsurugi. It looks like it's running at 252% after the game switches from 640x480@57 to 400x256@54.12. Try setting "multithreading 0" in mame.ini. If that didn't work, then try "changeres 0".

[mitsurugi]

Thanks for reply me. But if i change this, it would affect to all games, right?
what is the function of changeres and multithreading?
I was thinking multithreading is for x64 cpus like core 2 duo.

[mitsurugi]

I have tried disable changeres and multithreading but still accelerated.
I have put "triplebuffer 1" and the game speed is good!

I have the same issue with Carnevil. Seems like it wants to run at about 273% on my system. At that rate the sound is not warbling (but obviously a higher pitch). Only by setting triplebuffer to 1 do I get it to run correctly. I thought gmame was supposed to pick the right setting if triplebuffer and syncrefresh were both set to 0.

Seems like something is causing mame to go between 98% and 102% during emulation, which gives the weird sound. Setting changeres to 0 just results in a smaller picture, and setting the multicore to 0 does nothing.

Here are my options btw (this is at the 273% speed) and not setting triplebuffer.

Ah. I was having he the same issue with Arkanoid. Turning triplebuffer on seemed to do the trick.

[Calamity]

Are you guys by any chance using the -frame_delay option? If this is the case, then probably you need to increase its value, try 4 or 5.

[billfor]

I was using frame_delay 0.
I turned tripple buffer off and now when I increase the value of frame_delay the sound evens out, but the game still runs fast. As you increase the number it runs in the high 100s instead of 270%.
At frame_delay 9 is runs around 153% and then there is an abrupt change when I increase to 10 it runs at 98% (which is pretty tolerable).

Not sure why/how that works and why triplebuffer fixed it originally.....
