I started to patch this demo back in June and had most of it finished
after some days. There were some minor problems in the skyline
(timing) and the starwars scroller part which is why I didn't release it
until now. Today I fixed these problems and finished the patch.
I always liked this demo, classic mega demo style with some nice ideas
such as the skyline part, rather simple code but such a nice idea!
The code is quite OK, in one part the coder used a wrong hardware
register to enable the interrupts (DMACON instead of INTENA), it
only worked correctly by coincidence. Other than that there were
no real major problems. All parts were crunched with Tetra Pack 2.2
which is basically nothing more than a ByteKiller clone with an
additional RLE pass. I have relocated the decruncher to fast memory
to speed up decrunching.
If you want to listen to the loader tune you can use the ButtonWait
tooltype, you will then have to press either mouse button to quit
the loader part.
Enjoy the demo from HD.
