Is there something wrong with the character set or the emulation? I've never seen this game on the UK101/Superboard before but if looks like the graphics are displayed wrong, like there's an off-by-one error in the emulation of the character ROM or something, so that it shows one pixel from the wrong character on each line or something.
I am posting here a development version with greatly improved graphic resolution and more memory. I am not sure whether I should release it, because the glitchy graphics are still there.
There seem to me to be two possibilities: either the character set itself it corrupted, or the VGA rendering doesn't work properly. I am leaning towards the first possibility, because the problem only manifests itself in certain graphic characters; text display is always fine. I will make some enquiries online and see if I can fix the problem.
Eventually I would like to redo the display the "MiSTer way", but that will take some time.
