we're working on a complete rewrite, this time using wxWidgets
so far we got support for both bootloaders (the original one, for the atmega162, as well as the cpumod - x0xb00t2.x)
the actual firmware-related features are not implemented yet, so you can't backup/restore your patterns, but you can flash a firmware with this
as for the port name, on osx, maybe this would help:

and look for something like "/dev/tty.usbserial-BANNED"
if you don't see it, then something might have gone wrong
