Here's the patch for the second Megademo by Vortex 42. It was requested
some days ago and I spent about 10 hours the last 2 days creating it.
The bootblock intro is not supported (yet) as it uses quite some ugly
hacks in the code and also OS routines for drawing etc. I may support
it in a later version of this patch but don't hold your breath, it's quite
some work for not much benefit!
Speaking of OS routines, in part 2 mathffp library was used to calculate
the data for deforming the picture, I first tried to emulate it but wasn't
successful and after a while I simply decided to include the precaluclated
picture data in the patch. This might also be changed in a later version of
the patch but yet again, don't hold your breath!
Other than that there were a lot of ROM accesses to fix, these were mainly
used to generate random data for starfields and to set interrupts which made
the demo crash on anything else than Kickstart 1.2 machines. A lot of
blitter waits and other fixes had to be applied as well which took a fair
amount of time.
I have added ButtonWait support for the loader part, use it if you want
to listen to the loader tune. If enabled the parts won't start until either
mouse button has been pressed.
Ennjoy another classic from HD.
