Groovymame doesn't switch to correct magic resolution

[kirby_blue]

Evening Gentlemen!

As soon as I discovered the existence of groovymame, I traded my nvidia card for an ATI one! However, after setting everything up, I have a problem that I'm unable to solve.
Since I run Hyperspin, I configured Vmmaker to generate magic modelines. However, it also generated some (non magic) modelines which mess the screen up when used. (the left and right parts of the screen are inverted). I used ArcadeOSD to set one of the magic modelines as desktop mode (which works fine) BUT Groovymame reverts back to one of the non magic modelines. How come is this? Isn't GroovyMame supposed to switch to the best resolution available for the game?

I enclose vmmaker and groovy ini files.

Any help is greatly appreciated!

EDIT: I forgot my graphics card details:
Ati Radeon 9250 PCI -> J-PAC -> Hantarex 9000
I also added a picture where you can see what the 'split screen' looks like

Does groovymame do the right thing when you run it from the command line...

groovymame.exe romname

If so, then the problem might be your Hyperspin configuration.  I recall that I had to disable hyperlaunch or something similar.

When the screen splits like that, it means that the signal being sent through the J-PAC is out of range.
The J-PAC does that to protect your monitor from damage.

I *think* you should be using the "H9110" preset in VMMaker and your mame.ini

You should probably attach a log file from the game that is giving you issues like this...

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

Hi!

So I reran VMMAKER with h9110 as a preset and this time it generated 40 and some resolutions instead of just 12. Now Groovy switches to a seemingly suitable resolution (at least it's full screen) excepts that the games run way too fast.

Since I couldn't get groovy to print me a log (unknown command: -md), I copied what I could from the dos prompt for two random games that I tested: 88games and metal slug. Both run beyond their normal speed. It seems there's an error with DirectDraw but I'm unsure as to what it is...

Does it work correctly if you use D3D mode instead of DDraw?

I'm not sure if magic resolutions requires that now or not.

Well I'm currently away from home and am coming back mid-January so I won't be able perform further testing before then. Thanks for your advice. I'll keep you posted as soon as I get back home.

Hi kirby_blue,

New GM doesn't need the -md param to provide a full log, I removed that so that it was easier to get logs, now you only need to use the -v param.

Your logs show that the hardware acceleration doesn't work. This may be due to several reasons, being these the most probable:

1 - Badly installed drivers.
2 - A virtual driver getting in the middle.

This line in your log:
Video: Monitor 00260071 = "\\.\DISPLAYV1"

points to option 2. Are you using any software for remote controlling your system? That might be the issue, try disabling or uninstalling it.

You're right I'm running a VNC server so that if I mess something up and get no picture anymore, I can still put things back in order. Well, it seems that I'll have to give up on my backup solution then 

I'll try to disable it and I'll keep you updated as soon as I get back home.
