ubee512 artifacts - Under4Mhz - 13-05-2022 I've written a test program that writes colours to the screen. Mame is what I'm expecting, ubee in 512k mode shows these artifacts. Putting ubee into p128k mode shows the bottom half of the text flickering. What's causing the difference? I'm assuming it's some microbee hardware limitation the ubee implements and mame doesn't. RE: ubee512 artifacts - Under4Mhz - 13-05-2022 Nevermind, it's looks like the way I was banking in the colour ram. I was trying to write to port 0x1c to enable the colour ram, but I have been swapping in the attribute ram.
