I added it to that Segaretro page on 13/08/21, I also added it to Mame. Anyway I've since realised that Redump doesn't actually have a bios dat for Sega/Mega-CD so I guess this doesn't matter

Comes from a late UK machine (MK-4102A-50) with the smaller Sony-made pcb.
Find it here: https://drive.google.com/file/d/1HWc-XS … F2NaEuhdLt
