Change that code in "Picture": ldx #12 -> ldx #3 ;setup loop to topMargin sta WSYNC ;draw 3 (was 12) blank lines at top of screen That will give you exactly 262 lines (and also slightly less flicker :-). BTW: I have optimized the text display routine a little bit. Now you could display about extra 3 lines of text. If you are interested, drop me a mail. > Where would I look to figure out whether that's something I can reduce > to a more NTSC-friendly value (I assume 262 or 263 would be ideal...) ? Whatever you change, make sure that you create an *even* number of lines, else there will be only b/w on PAL TVs. Have fun!
