You can try Freeloader from Alesis. There are free Mac and Windows sysex tools at http://www.alesis.com/index.php?id=58,43,0,0,1,0

I haven't tried them myself as I always use the one built into the MIDI sequencer I use but they should work fine for you and they are free to try.

If the program won't recognize those .EMU files as sysex then simply rename them from .EMU to .syx That is why I did that myself when I put them up in my file archive. The .EMU extension was just what those Emu .exe tools were expecting.
