This has been on my "should be done one day" list for quite a while already.
I never really got around to creating this patch for one reason or another,
had a brief look at the code back in 2013 but then got sidetracked as usual.
2 days ago I remembered the demo and finally created the patch in a few hours.
The code was protected a bit (not too surprising if you know who the coders
are, hint: this could've been a Defjam and/or CCS demo!), some prefetch
tricks were used to disguise what the code is doing. Was fun to "crack"
and it was one of the reasons why the demo only worked on 68000 machines.
I have completely removed all protection code and "emulate" it in this patch!
Other than that there was some self-modifying code and other minor things to
fix but the code, specially for a 1990 demo, is quite good!
Some of the tunes need a while to start, this is not a bug of this patch,
it's the same in the original demo on an A500!
Enjoy the SID tunes and have fun with quite a classic demo which really deserved
the WHDLoad treatment.
