Quite a classic music disk here with good tunes if you like the style.
Code is quite good so most of the patch was finished after a few hours
of work, there were the usual replayer bugs to fix, a lot of blitter waits
to add and some other minor things to patch. There was one problem left which
kept me busy for (way too) many hours, the scroller in the main part only
worked correctly on OCS machines, on ECS/AGA it started to bug once a certain
scroll speed was set. I first suspected a problem with Bplcon1 and ended up
with a completed recoded scroller routine, however, the problem still existed...
After many hours I finally found the culprit, the DDFSTRT value was wrong
and caused different DMA fetches on OCS and ECS/AGA which made the scroller
bug out on anything else than OCS machines. Luckily I found the reason as I
can now easily fix the same problem in a lot of parts in North Star Megademo
2+3 which means these patches will hopefully be released soon as well.
There's a hidden DigiTek intro which is of course fully supported, you can
either enable it with CUSTOM1 or try to find out how to enable it yourself from
within the demo.
Enough babble, enjoy this classic from HD!
