====== Rasterbar Flash Screen Effect ====== A Rasterbar Screen Flasher routine by Wozza/CygnusOz ~ you can assemble via Kick Assembler! {{:base:rasterbar-flasher.jpg?200|}} {{:base:rasterbar-flasher_src.rar|}} You can achieve this effect in a number of ways, with obvious tighter code etc, but this is my poor version. When I first started coding back in the early 80's, Rasterbars were a lot of fun, but I remember nutting out a flash routine which I thought was very cool. m( I didn't do much coding after that, (too busy swapping, chasing girls and boozing) so after 20+ years (ahem) it's been fun to go back and re-visit. If you are learning to code basic ASM routines then this is a good start; you can get different effects by changing a few bytes. Muck around and play! Try adding in another IRQ for say, a scroller etc... ---- // autostart .pc = $0801 "Basic Program Start" :BasicUpstart(start) //set variables and locations .var colours = $0a00 .var timing = $0b00 .var pattern = $0c00 .pc = $0810 "Main Program" start: cld sei // setup a simple irq jsr $e544 ldx #>irq1 stx $0315 ldx #
