I think the best way to describe the graphics requirements is that if you had 2 meg chip ram and 4 meg fast ram on an A500 (with a math co-pro) it would also run.
It doesn't use AGA, it uses ECS, but it uses dpaint anims to show the animations, and streams iff's as well.
I need more people to write in and tell me their setup and how they installed it because I can only test it on my A1200.
Obviously it runs on my computer, so I will have to guess how you set it up. I can however - while waiting for people to write in - try a few things on my 1200 and give you an accurate description of how it starts up. I think I have a setpatch mod on disk as well, so I will research that and upload anything of use.
