What's an SCC?

You can read on the package of each MEGA ROM game produced by Konami (with SCC chip): "...new 8 voice polyphonic LSI Custom Sound Chip Mounted". 8 channels? The chip has only got 5 channels and the 3 other channels are provided by built in in evey MSX, AY-3-8910 PSG chip by General Instruments.

More info on the specs of the SCC can be found on the pages mentioned above.

This required ofcourse that you had enough RAM in your MSX2 machine to load those ROMs. To disable the game ROM in the cartridge, it was recommended to cut one of the game ROM's pins or make a kind of switch e.g. Technical info is here (By Sean Young) .
