Resolutions on arcade monitor

[mng70]

Hi there

I've recently installed Groovymame and some of my games aren't displaying properly on my 15kHz arcade monitor. Some games which should fill the screen horizontally look vertical such as Gigawing which should be 384x224(h). Other games that run at 384x240(h), 240x252(h) & 336x240(h).

So what I'm asking is how do I get the correct resolutions on some of these games. Do I have to add them manually somehow as Groovymame doesn't seem to display them properly.

Any help and advice is much appreciated.

Hi mng70,

In order to pick a resolution, GroovyMAME needs it to be available in the system. You usually get all required resolutions installed by using VMMaker (CRT_Emudriver) for ATI cards. Have you run VMMaker yet?

If you already completed that step and still having issues with particular games then get a log of these games as it's explained here:

Hi Calamity, no I haven't run Vmmaker. Is this a program I need to install? I have a Ceronix 29" monitor and the ArcadeVGA 3000 PCI-E card in my MAME PC. Do I just add the relevant line in the mame.ini - in this case CGA? Please advise as this is new to me.

Many thanks

Unfortunately, the ArcadeVGA 3000 is not supported by GroovyMame under Windows. You might want to try Groovy Arcade Linux instead.

Even if GroovyMAME can't create new modelines for the ArcadeVGA 3000 under Windows, it can still be used with the existing modelines to provide smooth scrolling (compared to regular MAME). Some members like Krick are using it with AVGA3000. However I don't know how good (or bad) the current algorithm for picking resolutions is working for the AVGA 3000 right now. It used to perform good back when bitbytebit coded it, but later changes may have introduced problems. I'm still interested in seeing mng70's logs to find what the problem can be.

This may help explain some of what you are seeing:

I'm more than happy to provide you with whatever you need if you can tell me how and what you need.

You only have to run this from command line:

groovymame.exe gigawing -v -md 4 >gigawing.txt

... and then attach the resulting file here, so I can see what's going on.

Thanks!
