Going back to when I had my first Vic I used to buy virtually every game available and I remember something along the lines of a game maker where you could set out your screen, set a default path for enemies and sounds etc. As far as I can see it does not seem to have been dumped so just wondering if anyone else remembers it? (and before you ask it was sold 25 years ago and the person I sold all my stuff to no longer has it all )
Develop-20 The Game Programmer's Toolkit maybe? I found a copy at Raymond's shop in Minneapolis last year. HERE you can download the program(s). I still have the manual scans somewhere, but I posted them in Megaupload some time ago, and maybe someone can send them to you via email.
