Old but still enjoyable demo that was mentioned on EAB a while ago, as it
only works on Kickstart 1.2 due to ROM access to acknowledge the interrupts.
Always liked this demo, so I created a patch for it. Code is quite OK, there
were no really bad problems to fix, a lot of OS routines had to be disabled
or emulated though, for example DoIO (which was used for trackloading) or
Text (graphics.library) which was used to write the text for the loading
screens. There also were annoying sprite problems, which I have fixed as well.
Not relevant for this patch (as all OS routines have been either disabled
or emulated), but still interesting enough to mention is the fact that in
many parts Forbid was called at the beginning, but instead of calling the
correct Permit at the end of the part, Forbid was called again.
Unfortunately, there is no fully working image of this demo availabe, part 7
is broken and has been disabled in this patch. If a good version of this
demo ever turns up, I will update the patch to support part 7 as well.
The latest version of the source for this patch can be found on
my Github: https://github.com/MK1Roxxor/WHDLoad_Patches/blob/master/Demos/WOT_Megademo2_WHD.s
Enjoy the demo from HD.
