Battlezone graphics only drawing for the left 1/2"?
Only thing I've done is tested the XY output on a scope to make sure my monitor was working ok and I get the same image on both.
It's not a collapsed vertical line where all the information is being drawn in that line, but it's like the screen is only drawn for about 1/2" from the left and then nothing more across the screen. I only have a few lines being drawn in the left 1/2" vertical strip which looks like the correct lines for what is supposed to be on the screen there... the mountains, horizon line, etc... (hopefully that makes sense)
I'm hopefully going to be able to work on it more tonight but I wanted to see if anyone had any ideas or has run into this before.
It's really a neat problem to me because I know the beam isn't scanning across every horizontal line like a raster display so I'm a bit stumped at why only the left 1/2" would draw. Can't wait to see what causes this.
