Description

The Sound Cartridge is a MegaRAM with a extra sound chip that was sold in Japan by Konami with the games Snatcher and SD Snatcher. This cartridge uses the SCC+ chip, an improved version of the SCC chip.

The Ram is 64kB only and can be expanded to 128kB to enjoy many extra software, but the case is difficult to open without damaging it a bit.

To expand the RAM to 128kB you will need to solder two RAM of 64 x 4 bits (41464 or 81464, 120ns).

It seems that there are two versions of the PCB: an older version with a wire on the back and a newer version PCB without it. Probably because the SCC+ could not address 128kB with the older PCB. More information about the SCC+ can be found here: http://bifi.msxnet.org/msxnet/tech/soundcartridge.html
