ACID 64 Player Pro is the sequal of Acid 64 Player and is a cycle based Commodore 64 music player designed for playing SID tunes on sound cards/devices that have a real SID chip (6581/6582/8580) on board like the HardSID cards and HardSID 4U USB device.

ACID 64 emulates the MOS 6510 micro processor, the 6526 CIA chip and partially the 6569 VIC chip to run the code of a SID tune and it controls the SID chip on the device for playing the Commodore 64 music.
