I found a site with a C64 emulator and LOADS of games (I'll dig out the link if anyone wants it).

I never realised that Way of the Exploding Fist II was the same game as Fist II!

I used to play that game non stop and I've been playing it once again over the past few weeks. I still can't work out what the point of the scrolls is and what's meant to happen once you get all the scrolls- if you could point me in the right direction, Nigel, it would be very cool.
