I have one of those! I got it on Ebay from a seller in Japan. I have open it up and checked the chips and they all looks original. No extra soldering or any strange looking chips. The case, cart, insert, manual are all original. And a few of my friends has them as well. They play fine, just a few differences <IMG SRC="smilies/spock.gif" border="0"> for 170 bucks, can't be that bad. Just like the VIC-A system from Korea. Everyone says they're not original. But, it checked out to be just fine. I'm guessing that there maybe other games that are like that, US, Jap, Korea, Germany ..ect
