Title: How do I get games in MAME to run at a different frequency?
Post by: javeryh on September 28, 2006, 01:44:36 pm: 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!!!

Post by: javeryh on September 29, 2006, 01:15:15 pm: 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!!

Post by: Howard_Casto on September 29, 2006, 11:16:26 pm: 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?

Post by: javeryh on October 02, 2006, 07:45:02 am: 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...
