Not hard. Just use Pokey's 16 bit mode which occupies two sound channels for one tone. Related to the "Driller" sound that means the third wave isn't possible any more while playing two 16bit ones...
Pokey example for this sound:
Nice example ! Those beginning sounds are exactly what I was thinking of.
I would put these sounds as background music. I do need explosions and laser sounds inside game so will have to try doing something that combines that.
quite close approximation is also available via software synthesis (look up SID player). Might be okayish for game startup screen.
Yeah, I thought about going that route, but am afraid I won't have cpu cycles for that... Game will be pretty cpu intensive (lots of drawing on screen).
Found some examples from Emkay here on forum (http://atariage.com/...okey/?p=1813218)
It has nice "noise" channel but I don't like starting tone that much... One in that Ultrazocker sap file is better.
Where can I find info on that "16 bit" pokey mode ?
