Newbie question regarding on how to program Japanese words to English

[Darunia]

I want to get into programming old Japan exclusive games into English, problem is that I don't really know where to start. I feel like it would be an interesting hobby to get into. What software do you use to edit words in a video game? I think I've heard people use something called a hex editor? What are some good video or written tutorials on editing text for games?

Choose a game first. Better choose a simple game with little text and no compression as your first project. The game can be stored as ROM dump, ISO image or data files and you have to workout how text strings and fonts are stored. Then extract the text strings and translate them to English. Edit the font graphics to English. In most cases, English text takes up more room than Japanese text so you need to find free space to put the translated text back in. Then you need to figure out the method the game uses to find where the text strings are stored and adjust that to correctly find the translated text. Once the game is playable, you need to create a patch for distribution.
