The kit is sold as DIY and requires soldering skills, please make sure you are confident in installing before purchasing. A video example of an install by RetroRGB is posted below.

The board can also be installed in a Sega Master System model 1 & 2, but there are no install instructions. You may however refer to other install pictures.
This board is recommended for install on the MD/Genesis Model 1 & not the Model 2. The Model 1 consoles already output good quality audio, however, the Model 2 has audio issues which I recommend to use the Triple Bypass mod bypass both the video and audio circuits together.
Whereas the RGB Bypass will on some consoles eliminate jailbars completely, they may partially remain on other consoles due to noise from the VDP. See here: https://www.retrorgb.com/genesisrgbbypass.html
Composite video is disabled after install, please use with a Model 1 MD/Genesis cable wired for CSYNC.
