official translation?
 

Just now I have seen pictures of a French language version of "Teenage mutant ninja turtles: the arcade game" on the NES. I am not sure if that "French TMNT 2 translation" is an authentic game: The title screen says "Teenage Mutant Ninja Turtles 2: Jeu'd arcade" . Shouldn't it say "Tortues ninja 2: Jau'd arcade" ?

You mean like this:

Ha! Do you really think that there would be an official translation by now?
Konami haven't even been able to get the rights to port that game (fully)
as an unlockable into their newer games, do you really think they'd bother
translating it for an older platform?

The deal is that, nowadays, with a little effort and perseverance, everybody
can translate any ROM they want, specially the older ones. If I'm not
mistaken, you won't have much trouble even to find tools that are already
done in order to help you into it.

But hey, don't be mad, here with me I've also got this game tranlated into
Portuguese-BR, Chinese and Russian. So, was I able to change your mind
about the POSSIBILITY of an official tranlation?

:)

I had a feeling it could be fake

It's posibile it's not....the TMNT logo is probably just an image....the text is what would be edited from version to version...but i dunna

copyright 2002?

IT IS FAKE!

Dude, it's not fake. It just isn't OFFICIAL. The images above are
from an actual ROM image. I've just "print screened" them for you.

Portuguese, russian, and chinese were also translated roms.

They are very real :)

Yeah, they are basically text hacks. I have several Translation hacks for multiple systems. (Mostly RPGs for TG16 and SNES)
