I finally got around to dumping the BIOS off the Aiwa Sega Mega-CD Game Unit CSD-GM1. The chip is labelled MPR-15768-T and reports version 2.11c. If anyone can find any differences between it and other versions that would be way past cool. I do not want to ever have to desolder a 40-pin DIP again though, but if I have to I know the best way to do it now. Below are the three videos of disassembling the unit, desoldering the chip (loooong) and finally dumping and testing in an EverDrive. Hope someone out there can use this or at least let my videos help them learn - there's more on my YouTube Channel. Download links are after the break too. * Download Link * The file is also available on McRetro.net via the files server (when it is online) or the Google Drive mirror.
