Just for the curious (not a critique!), they haven't implemented a filter yet:<br>
//filterOutput = IIR2((struct IIR_filter*)&filter04_06, filterInput);<br>
//IIR2(filter04_06, temp1);<br>
k=(temp>>8)+128;<br>
k+=temp1>>10; // no real filter implemeted yet<br>
<br>
So if someone wants to experiment with SID-like filters and wants a codebase to start from, there you go!<br>
(Sample rate appears to be 16 kHz on a 16MHz 16-bit chip.)<br>
<br>
Their full source is at (yeah they got the whole chip in about 400 lines!)<br>

Maybe this is old news, I don't know. Someone has an Indiegogo<br>
campaign<br>
to remake the Commodore 64 (or emulate it I guess, but in the same<br>
form<br>
factor). They list multiple SID chips in the list of features.  I'm<br>
not<br>
a huge SID fan myself, but I wonder how they plan to make it?<br>

"Multiple SIDs for stereo sound (6581 or 8580)"<br>
