Unfortunately, I just heard that one of those people, D.J. Peters, has passed away last week. He was active mostly on the FreeBasic forum, but he coded a lot of extensions for Basic4GL, too. I think you remember him.
Is there any plan to make the game SeedShip open source?
I read how, in 2019, someone asked for the source code to port it to a commodore 64. I think it would also be interesting porting it to FreeBasic or other languages.
