[XP] Custom Resolution with Fullscreen Script?

I'm looking for a script that allows custom resolution, a higher resolution that 640x480, and will also go fullscreen.

I've been trying this one and it goes to a higher resolution, but has a lot of problems otherwise:

I can't get it to go fullscreen, and a lot of the features that work in demo like changing the resolution in game won't even begin to function for me. Maybe I am not programming it right, but it is pretty complicated and there are like 6 different versions of the script. I tried inputting it straight from the demo and it still wouldn't work just like it did in the demo.

Any help would be appreciated.

From my experience, only one or the other appears to be possible.  I've seen scripts that allow for higher resolutions, but only in windowed mode.  Once those same scripts go fullscreen however, all sorts of problems occur.  So your script not going full screen at all may be intentional on the part of the script creator.  Our difficulty is that we dont have any access to that section of the code that controls full screen resolutions, so I doubt that it is possible.  Hopefully someone can prove me wrong.
