GH> *= $c000 GH>start dec $fb GH> bpl fix < this should be a bmi -not- a pbl as it is now GH> rts GH>fix lda #$07 GH>setup lda #$00; - setup $c040 GH> sta $fb; - smooth scroll poin I think you forgot the *= $c040 for the above, if you did forget then trying to run the routine by starting at $c040 may crash it.. GH>Well, it didn't work. :( I put the music (a DMC file) in $1000, the GH>text in $c800 (using I*c800), but it didn't work. Are you sure the GH>code is right? Apart from the change from the bpl to the bmi, it looks aok. As long as you are starting it with a call to setup, and you have defined the correct address for setup then it should work. Please try to be more specific when you say 'it didnt work'. Did it scroll the text but incorrectly, or did the screen shake, or did it just crash as soon as you told it to run? If it still doesnt work after those fixes, then I'm sending you the code on disk, coz I couldnt be stuffed with netmail! (: GH>PS BTW, is the code edited correctly? I have a nagging suspicion that GH>I may have edited the code wrong. What do you think? No, it looks fine to me. cya, Strobe/Menace --- Ezycom V1.05 00f90038* Origin: WOW BBS - Commodore Suport, Sydney's West (3:713/888) SEEN-BY: 50/99 54/54 640/316 711/807 808 809 929 934 712/623 713/317 700 805 SEEN-BY: 713/888 @PATH: 713/888 54/54 711/808 809 |
