Gary from OPA Posted July 11 Share Posted July 11 I was wondering if anyone tried the following, not writing anything to the VDP memory, only changing the background color. Can we change it fast enough or are we limited to only updating it during the blanking part. Quote #VoxelSpace taken to the extreme. Those pixels are drawn not by writing bytes into a framebuffer, but by changing the background color at exactly the right time, chasing the electron beam. That’s black-belt #m68k sorcery. 1 Quote Link to comment Share on other sites More sharing options...

I was thinking the same thing, but it turns out we can only change the background color a little faster than roughly once per scanline.

Tursi Posted July 12 Share Posted July 12 What @TheMole says. All the registers can be changed at any time, it just takes the 9900 a bit of time to get it done. 1 Quote Link to comment Share on other sites More sharing options...
