ACID 64

Wilfred Bos's SID player for HardSID and catweasel cards: instead of emulating the sid's sound, it "emulates the MOS 6510 micro processor to run the code of a SID tune and controls the cards for playing the music on a real 6581 or 8580". Everything the wiki knows about it comes from sidin's news pages (source: s-sidin-news-digest).
