i too owned this game and totally regret selling it, good move on keeping it. although you may not have purchased the overlay directly from them it came from (or at least the scan did) classicarcadegrafix.com when they were still arround, i remember sending them the NOS overlay to scan, the first overlay they sent to me had very "neon" greens in the bushes ( as yours does) that lined up with the bezel so i sent it back and they adjusted the greens. scan ended up on line for free
on the cab...its a data east like the ones used in Karnov, caveman ninja, etc.......so this kit was definately installed. i spoke with someone who worked from capcom NA and they told me the althought strider was primirally offered as a kit they did offer a "dedicated" cabinet which was simply was the kit installed in a first generation dynamo, these have the three sided control panel as used in forgotten worlds - minus the unique spinners.
