For sure. What it gave me was I think similar to the Amstrad version of Thrust and since I originally played it on a Commodore PLUS/4 I had to tweak it a bit. The fist version also had wrong gravity and rotation speed constants. But those were easy tweaks. Whenever I am bored or waiting for something more serious to complete I recreate games I used to play as a kid. I am currently working on Mercenary.
