You're confirming what I was concluding based on my limited graphical experience....
I may just have to forego having an actual "galaga bezel" for now, come up with something generic, then come back later when there is better artwork available.
This particular bartop project is a gift so I doubt the recipient will care if the bezel is not authentic.
I figured I would get my design and parts figured out on this one and then build one for myself later.

Guess I will move on to the control panel overlay.....that as a piece of Vector art that hopefully I can figure out how to resize and adjust to what I need.
And I figure the sideart will be a piece of cake.
