Before people start asking, please wait awhile for a translation, it WILL take awhile.
Btw how do they do it? Just open up the game and replace text?
No, there's a lot that goes with it.
Inserting text into a game is never easy without the right tool.
Actually, without a coded tool it could take quite a long time to insert the text manually.
You also have to change the images in the game to do menu translations.
Then you have to test it all to make sure it doesn't crash, text limit can crash a game easily, so you also have to look out for that.
If a person wanted to change the text, first they'd have to extract/dump it from the file but you need to know the file's compression before you can even see the Japanese or whatever language it is you're looking for. Then of course, you have to know the language you're translating it from (Machine translators are the worst idea ever to use on translations).
Hope that helps
