It’s exactly like that on C64. Bacco was a bit ahead of his time when he did it. Both starfield and scroller are multiplexed sprites and he used CPU to do the diagonal scroller (2pixels up, 2 pixels to the left) and sinus table to move scroller sprites horizontally by simply changing sprite.x position. I can’t find it on youtube, but you can run it in emulator and see for yourself: http://csdb.dk/release/?id=58654 I never “polish” anything in my remakes, actually I try to make it look as authentic as possible. This is why I also used his sinus table to… Read more »
Never mind the awesome scroller, note the vector over the starfield! That is absolutely crazy and should be technically impossible on the Commodore64 – everything over everything like on the Amiga. It means he must have used the processor to do OR’s which is even crazier that he managed to get it to run so fast. This intro shouldn’t be possible on the Commodore64, and yet, it exists. And this is not the only time Bacco pulled this off, but he is THE guy who pulled it off! Others have tried in demos 20 years and more since (2013 –… Read more »
This is really impressive and a great conversion, TStorm. But for some reason I don’t really feel this one, as a crack intro.
That’s a lot of action for a c64 intro… How did they even pull this off on that machine?
Is the scroller really like that on C64, or has this one had a bit of polish?

A bit ahead of his time? That is such an understatement, have you gone British?
He was 20 years ahead of his time and still unmatched. 20 years later and it still blows my mind.
It really is like that on the C=64!
Hence we came up with the joke “Bacco thought he’s on the Amiga”.
Wow, simply wow. Awesome!
That one awesome intro!
This is simply awesome, outstanding scroller. Definitely one of the top 5 c64 crack intros of all time.

pretty cool stuff, especially for a C64.
Now that is incredible for C64 – nice work! Fantastic tune too 🙂
Well, here it is. The best C64 intro!
Second one done by very talented and slightly confused Bacco, clearly mistaken his C64 for Amiga. 🙂
