Graphic scrolling experiment for vic 20 on youtube

[Ivanhoe76]

Browsing youtube I found this two videos uploaded by a youtuber named Andy Mucho. Take a look at them, they seems really amazing since they're running on our little vic20.

Interesting! If you are interested in sub-char scrolling of the VIC20, two years ago, I did some experiences on the vertical scrolling.

The result is Cavern Explorer: https://www.youtube.com/watch?v=JvhkRBfTAec

With that technique you can scroll what you want, but you need to draw the screen sufficiently fast in the raster interval to avoid flickering.

I played Cavern Explorer, a really good game with smooth scrolling and thrust effect, and yes I'm interested in vic scrolling but have no assembly experience to try something similar I only programmed simple basic games back in the days...

The right opportunity to start with it!

I should take a look at the source code of Cavern Explorer to understand something more about scrol:lol:

Vertical pixel scrolling is fairly straight forward.

Horizontal or diagonal is the challenge. I think Cheese & Onion is the only game to have pulled it off so far. I got it working in my SuperMario demo but struggled to overlay sprites on top of it - I need to re-double my efforts this winter.

You're right beamrider! Cheese and Onion is the only game that gets near to best platform games for other computers!
P.S.: Supermario demo????

[tonyrocks]

yes @beamrider! double your winter efforts please. I will send cookies to help fuel

Vertical pixel scrolling is fairly straight forward.

Unless it's with single line resolution via hardware only.

I've seen your youtube demo two days ago! It was reposted in vic20 group on facebook and it looks really amazing! Congratulations! it's something unbelievable if you think it's running on simple vic20!!!

Vuokatti (#3 MiniGame Compo 2004 1K series) is 1 pix vertical PAL only, though. Source link in youtube description
