Hit the same hiccup a few hours back.
Trying to run it in fullscreen, or with a filter above 3x, causes that error message. I too, would love a solution if anyone knows one.
Well, at least I am not the only one.
What are your specs?
For fullscreen to work, you must select a fullscreen resolution that your graphics adapter supports.
The game's original resolution is 320x240, scale that up to 2x and you get 640x480, this resolution is supported by pretty much any graphics card out there. But if you select 3x scaling, you end up at a resolution of 960x720, which is not supported by any graphics card by default. Nvidia drivers allow you to create custom resolutions like that, for all other cards you will have to stick to 640x480 and fiddle with your graphics card scaling options to get that image to full screen (and hopefully the correct aspect ratio).
Yeah, but the problem is that it doesn't allow us to play in fullscreen at all
. That is, regardless of the resolution. And 960x720 is fine but windowed.
