Watch out @nanochess ! I finally got the blue-screen to show on page 14 of "Programming Games For Atari 2600" using Atari Dev Studio and DASM, and soon I'm sure I will have a line drawn on the screen! (hopefully)
@fultonbot amazing! For drawing a horizontal line the PF registers, for a vertical line just keep active any of the visual registers.
@nanochess Ah, so as long as the register is not cleared, it keeps drawing vertically?
@fultonbot that's right.
@nanochess
just playing with the background for now, getting used to loops and some of the math ops
@fultonbot excellent! The best way to learn
@nanochess Thanks for being so supportive of my neophyte efforts Oscar, it means a lot to me.
