It is also known as the K051649, if used inside arcade systems.

Technical Specifications

• Channels: 5
• Channels 1-5: Each Channel stores the following 4 values: A 32-Byte Waveform, a 12-bit Frequency (= 4096 possible Frequencies), 4-bit Volume (= 16 Levels) and 1 Bit to switch the whole channel on/off.
• Channels 4 & 5: Share the same Waveform, which results in a total of 4 * 32 = 128 Byte of storage space.

• The Arcade Games used the SCC together with several other chips, see the list above for them.

Emulation

• MSX | MSX SCC Music can be ripped into KSS Files. KSS Files are used to store the Sounds from various Chips and Systems, and thus are rather common. A Plugin for Winamp 2.x / 5.x / Foobar2000 / MacOS and Java is MSXplug (Link). They also work fine in Hoot.
• Arcade | The Arcade Game Music works fine in M1. M1 is a music player which is based on MAME and thus supports a lot of Arcade Games. More about M1 can be found here.
