Hi there! Well, if you have the ROM space, a faster way is always: LDA (ballPointer),Y sta ENABL With ballpointer pointing to a ROM area organized like: .byte %00000000 .byte %00000000 ; As many zeros as kernel is high .byte %00000000 ... .byte %00000010 .byte %00000010 ; As many "enables" as ball is high .byte %00000010 ... .byte %00000000 .byte %00000000 ; As many zeros as kernel is high .byte %00000000 Voil`: 8 cycles constant! ;-) Greetings, Manuel Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://stella.biglist.com
