Change that code in "Picture":
           ldx #12 -> ldx #3  ;setup loop to
           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.

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!
