"Touching is good," but hacking? Not so much. Nintendo has gone on the war path against five Japanese companies that make their living helping users rip off DS games
. Of course, a primary use for such hardware -- such as the R4 Revolution, pictured -- is homebrew and emulation, but good luck convincing Nintendo (or any large console manufacturer) of that. Details of the actual lawsuit are slim, but Nintendo has brought along with it 54 Japanese software makers to lend a bit of gravitas to the suit. If you haven't managed to hack your DS yet, now might be a good time to score the requisite hardware -- we might be facing a scarcity before too long.
