F-22 Interceptor

I wondered if this old Genesis sim F-22 Interceptor at the Genesis Project was ported from a PC or Mac version. At the time I had a Atari 800, and when I saw this, I bought the Genesis and the F-22 interceptor because I coudn't find it on any other platform. If it was, it would be a good addition to your site.
