japanese to english?

is there a software that can translate jap gba games to english??just askin...

no. aside from the fact that the game would have to be decompiled, translated and then recompiled, machine based language translation of anything is very poor. Machines translate words individually, which when reassembled into sentences lack grammar and context; and as such make little or no sense, and in some cases bear no resemblance to the original sentence. Machines are just not capable of understanding and obeying the complexities of human languages, nor can they deal with context, which has a significant bearing on language.

What loony is trying to say is that you're better off with a fan translation. If such a thing exist of course.
