Today I received my NES Super Mario Bros. 2 from the Netherlands. Unfortunately I was under the wrong impression that the NES UK/AU (PAL A) was able to play games from all PAL regions (PAL A, PAL B) and upon trying to load up Mario 2, I found that this wasn't the case as it's PAL B.

I am never one to give up so I started looking for options. I know about the typical Region unlock mod that most people use on the web which requires you to literally break the lockout chip connector on the NES Board. I am not a total purist but I don't like to permanently modify vintage stuff either so I searched for a less intrusive option.

Luckily I found this website that shows you how to do the Region Free mod with just linking some solder points with two wires. Very easy to apply and also nothing is permanently changed so it can be completely undone if one desires:

Tried it on my NES and I was able to load the PAL B Super Mario 2 with no issues. Hurrah! for that person who originally thought of that mod back in the mid 1980s and the article author for sharing it!
