Re: scroll routine $e975 (59765 in basic) doesn't work reliable for me

yep, i understand that for the basic start screen or basic lines. but here is an example code (i'm afraid i've mixed up 'up' and 'down'): *=$1001 !byte $0b,$08, $00,$00, $9e, $34, $36, $30, $30, $00,$00, $00 SCROLL_DOWN = $e975 SCROLL_UP = $ea08 *=$11f8 ; some initial things lda #9 sta $900f ldy #21...
