Another one pixel scroll

Recommended Posts

nice demo, why do the chars seem to have one pixelcolumn missing (=black)?

 

Thanks!

 

I noticed that! I think it's because the copy from CPU to VDP ram is slow, so the leftmost characters are defined *before* the rightmost ones.

So they scroll left one pixel before the next character is scrolled and this makes a black column appear.

 

If I could synchronize the transfert with the display... But I don't know how to do.

Very nice.

 

... seem to have one pixelcolumn missing

 

I would definitely have to say that it's a programming error, and one that can be resolved. I even think I ran into the same "effect" (error) when doing my Hellraiser demo back in April 2005.

Well, you were right, that was a bug in the program..!!

I fixed it and posted a new video with colors inverted.

 

 

Thanks for pointing at the problem.
