I recall reading there are a lot of fakes out there, and he says he searched hard to be sure he had a real one. I recall the R4 people being pissed saying they'd try and break the fakes with a firmware update or something. Is there a way I can tell this is real or not just from appearances w/out tearing it apart? Also would you say that $40 is fair in cash for it. Seems he picked it up and never used the stupid thing really much at all but just a few times because he got this red ds box set with those pokemon rogue wannabes in it and finished them, then couldn't find anything he liked using the R4 for so it's all for sale on craigslist local to me.
