Hi there! > >(I think something like that does the starfield in Star Fire...) > YOU THINK ????? > Who programed that game ? LOL > --Happy_Dude Ah, Ok. I was just too lazy to look it up for sure :-) Here' the common part that every 2LK iteration of the Star Fire kernel does at the beginning: ;--------------------------------------------------------- NextLine STA WSYNC ; Wait for horizontal sync STA HMOVE ; Horizontal Movement ; Reset stack to RESBL TXA LDX #$1F TXS TAX ; Draw starfield LDY vline CPY yposBackup+2 PHP CPY yposBackup+1 PHP CPY yposBackup PHP LDA crosshair,Y STA PF2 ;--------------------------------------------------------- That is some ~35 cycles out of the 2*76 available, which already completely handle both missiles, the ball and the PF ;-) Greetings, Manuel ---------------------------------------------------------------------------------------------- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
