How to properly setup $fffe interrupt ?
Good day to you all, I have a bit of a problem so... :
I found some old code of mine on an old tape and transfered it to PC and want to compile it using tass and try it on CCS64 or VICE. Im sure code worked 15 years ago, but now... :)
So why this happens...
"sei
...
lda #<irqsr
ldx #>irqsr
sta $fffe
stx $ffff
...
cli"
I watched this code in VICEs debbuger and imidiatelly when sta $fffe is done there is NO change in $fffe ?
same with $ffff
So when cli goes, my prg just goes to $ff48 and my interupt routine is never executed...?
So I would be very gratefull if someone can write just some small piece of code that makes my routine go off in regular timed intervals (5-20 times a second...).
I read some other posts but cant get it to work...
thanks... |

Is it demo group ?
is it a joke :) No offence intended... :)
p.s. Monte thanks...
Hema is the #1 crack/release group these days. Groups like Onslaught & Triad have nothing on them! |
