I tried to call sound effects from assembler but no luck, it keeps silent.
* My game has disabled the kernal und the zeropages FD-FF is not used
* I exported the sound prg file to $e000
* In my program I set the volume to 15
* I called once:
lda $0 // effect
ldy $0 // channel
jsr $0e4a
* I used my own raster routine and called jsr $e2a9
Any idea?
