This cabinet was left at my house when the last tenants left... they said they were taking it to Goodwill if I didn't want it. It's set up as Ninja Gaiden right now but it appears to have originally been Defender. The framing around the screen is from a Defender machine... and the shape of the cabinet looks exactly like it as well.

Here's a Defender cabinet...



And here is mine...











How hard would it be to convert it back into Defender? It looks like all they did on the outside was paint over the side art and change the inlays. The cabinet itself is in pretty good condition but the marquee light needs to be replaced.
