Pseudo Hi-Res Mode is a transparency technique that displays the Main Screen and Sub Screen at the same time without the use of color math. It is enabled by setting bit 3 of SETINI (2133h). Columns of dots with an odd horizontal position are drawn by sampling a subscreen pixel, and columns of dots with an even horizontal position are drawn by sampling a main screen pixel. [3] A CRT televsion blends the adjacent dots together, creating the transparency effect.
As of 2022, there are no tools for working with psuedo hi-res mode. [2]
