Translation software?

I was wondering if there are any translation sofeware for DS. Those that translate from japanese to english. Not those type of dictionary games but those that actually help you translate the Japanese language in games to english. cause some japanese games seems really nice but i dunno how to read japanese and i don't understand japanese.....

Google for=
"*name of game* ds language patch"usually gets it done

Not really any GUI tools out there at the moment (from what I know). Manual editing will be required, sorry. There's a topic on Gbatemp.net in the Rom Hackings board which will give you knowledge specific to the DS.
