That's a problem for C64, from what I've heard...I think the SID chip
hasn't
been reverse-engineered...
There are several modern SID replacements now.. The new hotness is the
ArmSID which is a complete ARM based computer that emulates a SID chip
and fits into the original SID socket. :D
Some others are SwinSID/Nano SwinSID, BackSID, FPGASID, SIDKick...
