Phew, took a while but finished reading through this complete thread...
Firstly awesome work leathered; well done indeed with all this and your devotion to a dream. Looks really cool and do hope that you finish this (which I'm positive you will)
Also nice work turrican3 and dlfrsilver (plus others that have helped along the way).
I'm a massive arcade head but also love the Amiga so nice to see a project like this. If I'm honest I thought the original Amiga version by Richard Aplin was pretty good and enjoyed playing it but of course nothing beats the arcade original
How close are you to completing this now?
