Sega CD multi-BIOS EPROM

Pre-flashed Sega CD multi-BIOS EPROM chip for the Megamod


This EPROM is pre-flashed with all three original region BIOS files (EUR/USA/JAP) without any modifications on them. All original screens, everything is stock.

They are switched over via pins 38 and 39 on the EPROM. These pins connect to the MegaMod board and are switched automatically from the Genesis/MD system upon region change.

Installation requires excellent soldering and modding skills. Pins 38 and 39 are wired via two unused pins on the expansion bus connecting to the Genesis/MD, and then to the MegaMod.

Warning! I take no responsibility is you mess this modification up! Do at your own risk, or get someone more experienced to do it for you!
