Here is the other application:   http://rapidshare.de/files/11976996/DS2key_osx.html   Pretty basic at this time, will add features later.   DPAD is binded on asdw, and the others buttons to 1-2-3-4-5-6-7-8   Tried with nestopia, work well (just remap the keyboard).   To test, just give focus in a window where you can input text.  Still a console version, first time I use Xcode, so icons and fancy stuff are for the next release.   Enjoy!
