Neo Geo CD regions

I recently bought a Neo Geo CDZ. For those that don‘t know. It’s a Neo Geo CD with faster loading times than the original front-loaders and top-loaders. Something that's interesting about Neo Geo CD games is that most if not all games from any region come with at least 2 region versions on the disc. Usually, US (North America) which is in English of course, and the Japanese version.

One game that I know has 3 versions is Puzzle Bobble or Bust-A-Move in North America. You can easily change the region with jumper wires on the board. There's even a legend that tells you where to put the wire for each region. I made a video showing the 3 versions of Puzzle Bobble on one disc. https://youtu.be/b-wy7TEs--o
