thanks to all for the apprciation here. It does not take long to remake these and also, after a couple of them, there is a lot of code reused. For example a sine scroller is always the same, only the frequency/period and amplitue changes... no big deal.
Anyway there are plans to have the code for all of them available soon. So other coders can get inspired and remake other cracktros as well. But I would like to clean the code first, so it can be comprehensive for beginners too.
