Same for me, loved this game as a kid and spent many a guilder in it and Tron got me into 3d to begin with. Trying to do 3d on a zx spectrum is no joke. I believe it was VU3d or something haha, memory flash back.
Anyway you are the blacklight king, this was my first jump into getting the blacklight effect. And there are a few more things I will update, but sometimes it’s good to step back a bit. And want to get started on my next cab soon, don’t have as much time to do these as I would like.
