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.

What’s new in version v3.0.3:

New:

• Support for the new HardSID USB devices: Uno and UPlay.
• Auto detection of turned on/off USB devices.
• Added sorting on column of every grid.
• Emulated SID reading.

Improvements:

• When performing e.g. mute/unmute, filter on/off or pause then no time gap isn’t noticed anymore while playing on a USB device.
• Seek bar is always going smooth now and still synched with the 6510 CPU clock.
• Improved fast forward.
• HardSID.dll isn’t required anymore for USB devices.
• Many small improvements.

Fixes:

• Works now without administrator rights.
• When using dual monitor ACID 64 will now be centered on the screen instead of the desktop.
