You don't have to hold off, I just wanted to see if I could make this:
I took the pattern off of the manual. I should have said, I can have the Gun Nac... Stuff ready in a few weeks. This should be the final piece you need to do a near perfect F2 cover.
Excellent work! If you needed more of the pattern, though, the back of the manual has nothing BUT the pattern (well, that and the Taito logo in the middle). I was contemplating scanning the back for you as well but I figured you were more interested in the front art. Anyway, looks great! I'll get to work on the cover, then!
