How do I get games in MAME to run at a different frequency?

[javeryh]

OK, I have the Happs Vision Pro VGA/SVGA monitor (http://www.happcontrols.com/monitors/491337vp2lg.htm) and some games give me an "out of range" error message when I try to play them.  Examples are Tapper, Popeye and Mortal Kombat II.  Is there any way to get these games playable on my monitor?  Is there a setting I can input for each game that is doing this so it will run in the proper range of my monitor?

THANK YOU!!!

Thanks... for each game individually or mame as a whole?

OK, I'm going to try and walk through an example...  I am running "mspacman" perfectly with no modifications or special configurations other than specifying "-ror" so it rotates 90 degrees.  According to MAWS, mspacman runs at a resolution of 224x288 and at a frequency of 60.606060Hz.  Everything works perfectly for this game. 

I'm also trying to run "popeye" however I get an "out of range" error message on the monitor.  According to MAWS, popeye runs at a resolution of 512x448 and a frequency of 60.000000Hz.  How can I instruct my monitor to display this?

Would the command "-resolution 640x480" do the trick? 

Any help would be MUCH appreciated.  THANKS!!

Anyone??

yeah that'll work

You'll need 640x480@15 though if it's an arcade monitor.  For the record though It'd try a different resolution as 640x480 usually has to be interlaced to display on such a low frequency. 

This might be a good question to ask over at ultimarc.

Thanks a lot.  Well, the "-resolution 640x480" seems to work on the games that are "out of range" so far.  I've tested Popeye, MKII, Tapper, Punch-Out!!, Super Punch-Out!! and a couple others.  However, is there any reason why these games feel like they are running a little faster than what I'm used to?  Maybe I'm going crazy because it's so late, I'm having a party tomorrow and I wanted this thing to be playable...

Do you have a recommended resolution that I should try?

[Howard_Casto]

Do you have "throttle" turned on?  Because you should.

I tried toggling the throttle on and off (F10) and I definitely have it set at the slower speed.  I guess Punch-Out!! in the arcade is a lot faster than it was on the SNES like I remember it...
