Hi

I had a look at the intro, and basically I see a problem with how STE 
DMA sound is set during replayer init :

move.b    #1,$ffff8901.w
move.w    #$7ff,$ffff8924.w
move.w    #$401,$ffff8922.w

Replayer is "undead ym tracker", but this looks like a bug in the replay 
: it starts DMA sound, but it never set start/end address, so this will 
just play the content of the whole RAM :(

Are you able to check this on a real STE, I'm not sure the sound will be 
correct either ?
