MegaDrive

An Open-Source HardWare (OSHW) recreation of the Sega Mega Drive

The design tries to be a 1:1 recreation of the original IC BD M5 PAL board.

Tips if you decide to make this/get it made

The dimensions are 240x191mm.

You will have to source the 2 SEGA custom chips from either a dead board or a chip dealer.
