Possibly... But the 6532 is not a mixed signal chip like the SID so it 
could be done in one of those programmable logic devices and be a 100% 
replacement. From what I could find the FPGA2600 project does have a 
VHDL core for the 6532. I don't know if it's complete since the 2600 
didn't use all the features of the chip (no IRQs).
