As long as it is the right size it doesn't matter on format, but png would be fine.
I don't have any color details because this piece is unobtanium so the best I could offer is to scan. Only thing I know for sure is that it is silkscreened.
My idea is to 300 DPI scan the side that isn't warped to get the crowd image. The measurements of the warped area is basically 6 inches by 1 13/16 inches. So the final piece should be 6 x 1 13/16, with a black border, and a clear window with the word GOAL in a block font inside the window. Yellow and red border on the clear window, and crowd fill for the rest. I'd have to get better measurements for the location of the clear part.
I print that on white waterslide decal, put it onto PETG, And then I can cut the warped piece off the large piece in the picture. Now I have two pieces that I can put onto the game, the good right side, and the new left side. I'll post a better picture of the plastic on the game to see if it makes more sense.
I've done this with playfield art and simpler plastics but I have poor photoshop skills. Also I'm running version 7.
