I used to have this hobby. It's taking old console-based video games and altering their data on my computer. Some games made in Japan are never translated into English. It's possible to alter them so that they can be played in English. Other times, you can alter a game to whatever you want it to be.

It's obviously a lot harder than it looks. I didn't make this a page as a tutorial or anything. If you wanna know how to do what I've done, look elsewhere. This here is merely a display of my contributions.
