Hacking a region free Sega CD BIOS into a Genesis cartridge - Part 1: Desoldering a bad sports game

I completely ruined a Sega CD trying to desolder the BIOS chip to replace it with a region free BIOS chip. At the same time, I got a killer deal on a model 1 Sega CD, so I especially don't want to ruin it. The Genesis should still boot the Sega CD BIOS if you burn it to an EPROM and plug it into the cartridge slot, so that is precisely what I am going to try. Let's see if I'm successful or not in real time!

Maybe I'll rip the traces off of this board as well and you can laugh at me.

In case it wasn't evident, this video has a ton of newbie mistakes and is not a good example of how to desolder DIP ICs. My advice is to spend $20 on a desoldering iron/pump and to add solder to all the pins before starting. It will be a lot better.
