Dissatisfied with the Mythic Game Master Emulator - too fiddly and too slow - Spacejacking at Tiny Solitary Soldiers hacked together his own solo roleplaying game system and I gotta say, it ain't half-bad.
I personally haven't run into a problem with the GME either fiddly or cumbersome, but I think part of that comes from using the Flash version of the Fate Table - it works as fast as I can type the questions - so I can see why a more streamlined version appeals.
