I worked a deal with the O.G. of YT gaming pick up videos, bizzNES17, for some non-working games and make my best attempt to bust through the repairs as quickly and efficiently as possible. bizzNES17 channel link: / bizznes17
Great video. I just found your channel and enjoy seeing game repair work. One small suggestion. You might consider doing each game as it's own rapid fire repair video. Not only do you get more content, but it would make it easier for others who might be having a similar issue with a specific game to find your repair.
By the way, just a little information. The cartridge slot is actually region locked just like the c. D so if you have A us only action replay. It will not work in a Japanese Sega Saturn.
