Here's a tought. GK1 supports 640x400 graphics, but the backgrounds are 320x200 and look really chunky on modern computers and don't justice to the original artwork at least in my opinion. So, I decided to extract a few images from the game and retouch them a bit to see whether they would scale to 640x400 nicely. I played around with a few images for few minutes and sure enough they scale up nicely, if coming a bit darker. The next obvious thing would be to properly re-paint the images (at least the parts that still are blurry), but I didn't want to do that much work without first asking someones opinion that would it be possible to inject these images back in to the game somehow and with the aforementioned resolution of 640x400?
Here's what moonbeams place looks like original scaled to 640x400:
And here's the retouched and scaled 640x400:
Before making any comments about the quality of the retouched one, it's nothing final, it took maybe five minutes to get that.
Now, anyone, do you know if what I suggest is possible?
