Colour Flashing Notewriter Style

Have you saw programs like Face Noter, Octanoter, etc. All those programs use a special extra colour mode, to activate char flashing. Some of you may find it to be really difficult to understand how it works, but it is actually *that* easy to remember. All you need to do is switch $D011 to $5b to get extra colour mode, and create a colour cycling routine. Here's a routine for it.

;Flashing colours in EBC mode

flashpt = $02

           !to "flasher.prg",cbm
           * = $0810
           lda #$00
           sta flashpt
           sta $d020
           sta $d021
           lda #<irq
           ldx #>irq
           sta $314
           stx $315
           lda #$7f
           sta $dc0d
           lda #$5b
           sta $d011 ;Swich on EBC mode
           lda #$01
           sta $d01a
           rts ;Just end here for now
irq        inc $d019
           jsr flash
           jmp $ea31

flash      inc flashpt
           lda colour1,x
