I just downloaded the High Voltage Sid Collection (HVSC), which is a collection of sid files, which is files with music dumped from the C64. HVSC is one of the largest and most accurate computer music collections known.
The big thing I found today was that Sidplay was updated to version 2.5. It was a revolution, this is the most accurate SID emulation I’ve ever heard.
The MOS Technology 6581/8580 SID (Sound Interface Device) is the built-in Programmable Sound Generator chip of Commodore’s CBM-II, Commodore 64, Commodore 128 and Commodore MAX Machine home computers. It was one of the first sound chips of its kind to be included in a home computer prior to the digital sound revolution.
Together with the VIC-II graphics chip, the SID was instrumental in making the C64 the best selling computer in history, and is partly credited for initiating the demoscene.
