Please note: This is an advanced mod that requires soldering skills.
This mod kit updates your older version of the SD2SNES cartridge to the latest Rev.H version.
Older version of SD2SNES cartridges cause MSU-1 compatible games to have very quiet audio. Installing this kit on your SD2SNES cartridge fixes this issue.
