i downloaded an atari rom pack, and i came acroos this in it, its called "Atari Point of Purchase" and it shows the atari logo and the colors are going upwards, and i was wondering how would i recreate this? it'll be a cool effect to have in a game. here's the .bin:

You can easily accomplish this in ASM, however to do color changes in batari Basic you need to set the player colors per scanline which requires you to override the drawscreen function with your own. This way you won't have to setup player0color tables for each scanline color, per frame!

Right now there isn't an easy method for these visual effects that I know of.

I can't find an easy method to do this without replacing routines.

I'd say the easiest way via bB would be to store the players' color tables in the Superchip RAM. From there you'd have multiple options of transforming the color scroll dynamically.

dang i was hoping it had to do with something with the flashing colors like

 u=u+1

           COLUP0 = u
