There alot of japenese games out there and not many will come to america. I was wondering if there is any way you could translate nds japenese games into english or have some kind of subtitles for english? i know that but is there a patch or anything for a emulator that can translate jap games into egnlgish words or subtitles.
not automatically, no. some fan made translations exist, but creating them requires a lot of skill and time (and humans translating the text)
No, because the text you see in a game is a special font that was created by the people that made the game. A patch that could identify a font in-game and translate it is ludacris.
