SD2SNES upgrade board/MSU-1 volume fix service

Available now (handled by our partners BetaGamma Computing in Greece). Please allow for shipping and processing delays due to slow post in Europe and technical issues at the Greek post office. UK customers MUST e-mail us first about ANY mod work (except NI).

All repair/modification work is carried out subject to our terms and conditions. Once you have placed your order, details of where to ship your hardware will be sent to your e-mail address. Prices do NOT include return postage.

This service will upgrade your SD2SNES cartridge to the latest revision. If you have an older revision of the cartridge you may have noticed the audio in MSU-1 games is rather quiet. By purchasing this service we will fit our SD2SNES upgrade PCB, upgrading any revision of the cartridge to revision H, which fixes this problem.

Additionally, if you have a revision E board or earlier, you can order the revision E upgrade too. This small additional modification will prevent picture noise problems on 1-chip consoles.

To find out what revision of SD2SNES cartridge you have, carefully open the cartridge shell and look at the text above the battery. If you have a revision H or newer cartridge then you do not need this modification.
