Guess what I did when I arrived (very early as usual) at work today. :)
Always nice to start the day with some fun coding so I just patched
this demo which was released at the Maximum Pleasure party in 1991.
Code is very clean, only some minor things had to be fixed such as
the usual replayer bugs and stuff like that, some blitter waits had
to be added too in the init parts. The random generators relied on
the raster beam position so they produced not too good results on
fast machines and had to be recoded too.
The Bplcon0 color bit was never set, this had to be fixed too of course
but other than that this was quite an easy patch to do.
Most of the files were crunched with PowerPacker, I have relocated
the decrunchers to fast memory for better speed.
The demo is short (just 4 parts plus intro) but nice, the loader part
is quite nice as well. It features progress bars for loading/decrunching,
I have disabled the progress bar for loading for obvious reasons.
ButtonWait is supported for the loader picture, if enabled the demo
will not be started until either mouse button has been pressed.
Since the intro is quite long I have added an option to skip it,
this feature can be enabled with CUSTOM1=1.
The demo can be downloaded here:

Enjoy the demo from HD.
