Still bothers me that these guys are charging $30 for shipping this little unit. Add to that the cost of the controller (if you decide to go that way), and we are talking about 260 bucks.
For that, you can buy a non 1chip with an RGB cable and an OSSC, which will also allow you to use a Genesis, Saturn, Neo Geo, PSX, PS2, etc. through HDMI, out of the box. If you already have a SNES, it makes even less sense to go through this as opposed to just spending the money on the OSSC and an RGB cable. Not to mention you are playing the real thing and not have to deal with the growing pains of something that was reverse engineered, regardless of how accurate.
