I recently obtained both a n64 and NES everdrive for those systems. My next was going to be SNES, and I found this while looking for cheap prices: http://www.ebay.com/itm/Super-Everd...7065?pt=Video_Games_Games&hash=item3a8c204079 I've been in and out of the collecting scene long enough to smell potential clones, but I wanted to make sure since I can't seem to find any more information.
Yes this has been discussed before these are Chinese ripoff clones based on older versions of EverDrive without permission and poor quality, you will likely be ignored for support or help (I have seen it happen) from Everdrive / Krikzz supporters and community. Stick to distributors like RETROGATE, it is worth the extra.
