How to Mod Your Super Nintendo
Many of you probably already know this neat little trick to get your American SNES to play Japanese Super Famicom games. But since I only learned of it a couple years ago, I thought I’d post some easy-to-follow instructions for those who haven’t yet given it a try.
Modding your SNES is about the easiest thing you can do. There are no tiny mod chips, no soldering involved, no installation of hard disks, and no need to mangle your console. In fact, all you’ll need is a pair of pliers. I used a needle-nose pliers as it allowed me to get in there do the job without any fuss.
First, let’s take a look at what the issue is.

Pictured are the backs of two cartridges: on top we have an American SNES cart, and below it is a Japanese Super Famicom cart. These carts are different in a number of ways, the most important of which are the two little grooves on either side of the bottom of the American cart. Notice how those grooves are missing from the Japanese cart? This is what prevents us from playing Japanese carts on our American SNES. Take a look…

Alright, pictured above is the cartridge slot on the American SNES. Notice the two tabs on the top left and top right of the cartridge slot? Those line up with the grooves on the American cartridges. Because the Japanese carts don’t have those grooves, they are unable to fit properly into the American console’s cartridge slot.
The solution seems pretty obvious, doesn’t it? That’s right, we’re going to take our pliers and rip those little tabs out of there. Don’t worry, as long as you’re careful, no real harm will come to your SNES. In fact, you’ll never even notice they’re gone. So let’s get to work.
