Recently, a user sent me a link to an interview by the former website, JeuxFrance, on Mega Man Battle Network 5 DS. They spoke with Takeshi Horinouchi & Tsukasa Takenaka, Producer and Director of MMBN5DS. Apparently they came over and brought with them a debug build of a European translation of the game. They posted a picture of the game running on a Nintendo DS (though it also ran on a TV, but the shot is not clear enough) I certainly have never seen anything like it. The interview on its own is interesting, but this really catches more attention. The game has a debug mode enabled. The final version of the games have no debug mode which can be enabled and the tiles it uses certainly aren't there. I took the screenshot and annotated it to explain the debug display to the best of my ability.
