GroovyMAME sound problem

[shrunkenmaster]

I've just installed groovymame32_0151 and crt_emudriver 6.5 and am VERY impressed with my TV's picture! However, I'm having an audio problem. The sound seems to be changing pitch, or slowing down and speeding up. Can someone tell me what's causing this? I've set up GM & the driver according to these instructions:

There's nothing else on the PC except TinyXP (clean format/install). The .ini file is below, let me know if you need any further info!

If you're experiencing problems with a certain game, please create a log and post it when reporting the problem. This will provide most of the required information beforehand and will save us from asking you to post a log, which depending on your time zone may delay the answer by a couple of days.

Steps to create a log:

- Run GroovyMAME like this:

Code: [Select]

c:\mame_folder>groovymame.exe romname -v >romname.txt- Upload romname.txt as an attachment to your post. Please don't paste it inside the edit box as it makes things unreadable.

[cyb]

what kind of cpu do you have? my core 2 duo system does this when it doesn't have enough horsepower to play the game at 100 percent speed.

[shrunkenmaster]

Thanks for the replies guys. A bit more detail:

CPU is a Celeron D 2.93GHz, 1.5Gig RAM. Trying to run Power Drift (pdrift.zip). Using a UMSA scart converter to a TV.

Have tried creating a log using:
(START) (Run...) C:/MAME/GROOVYMAME.exe pdrift.zip -v pdrift.txt
and
(START) (Run...) C:/MAME/GROOVYMAME.exe pdrift -v pdrift.txt

Nothing seems to happen, save for a quick pop-up black window. Where should the log file end up anyway? I did a search for it but nothing seems to have been created. I'm not that experienced with Windows, so please allow for this!

Do this...

(START)(Run...) CMD

...to open a command prompt.  Then type...

CD c:/mame/

...to Change Directory into your MAME directory.  Then type...

GROOVYMAME.exe pdrift -v >pdrift.txt

...this will create pdrift.txt in your mame directory.

[shrunkenmaster]

Hey krick, thanks for going easy!! Now I can see it's a terminal, and just as fussy as OSX...

When I enter:
GROOVYMAME.exe pdrift -v pdrift.txt 
I get:
ERROR: Unknown Option: pdrift.txt

I can run pdrift from this command line ok, so I'm in the correct directory using the correct spelling. Just to check, the -v is a MINUS followed by a lower case V ?
Sorry again for my PC ignorance.

[krick]

The command line is missing a greater than character.

GROOVYMAME.exe pdrift -v >pdrift.txt

I corrected my last post.

[shrunkenmaster]

Cool, here's the file.

Hi shrunkenmaster,

It's probably not a problem with the sound but with the game speed. While in game, press F11 to see if the speed stays at 100%. If it fluctuates, it probably means your CPU is not capable of running the game with v-sync on. Try enabling -multithreading and -triplebuffer for the particular games where you see problems.

[shrunkenmaster]

Hey Calamity, thanks for that, although the options suggested made no difference. I've had regular MAME 0.106 running fine on this PC with soft15Khz, but the picture quality seems so much better using GM/CRTEmu. Can you recommend a way forward for using 0.106 with CRTEmu, or something else suitable? I really need a stable build as it's for my original Power Drift cab and I desperately need to drive like a lunatic 

[Calamity]

No problem. Try ArcadeMAME: http://id4retrodev.blogspot.com.es/

(it's based on v0.106 but modified to use SwitchRes).

[shrunkenmaster]

Hey Calamity, tried the ArcadeMAME build and all is looking - and sounding - great!

Thanks for the input all, it's really appreciated. If you're ever in the south of England pop round for a nice cup of tea and a few games

I'm happy that ArcadeMAME is useful for you , thanks you Calamity for remember it!

[shrunkenmaster]

And special thanks to you, ID4! 

[ID4]

Do you use it standalone, or in combination with switchres via ArcadeMAME.exe wrapper?
