ACID 64 player
ACID 64 player 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 PCI cards and the HardSID 4U, Uno and Uplay USB devices. It also supports network devices that emulate the SID chip like JSidDevice that is part of JSidplay2.
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 Commodore 64 music.
This project started in 1995 with the SidCard. The SidCard is a hardware module with a real SID chip that can be connected to the parallel port. However, this hardware project is discontinued. The software written for this project is ported to Windows and supports now all the HardSID cards/devices and software devices connected via a network interface.
