It actually un-UPX-ed just fine for me. What version have you been trying?
It disassembled nicely after that. The only other obfuscation (apart from
quite a bit of wild jmp'ing around) is the rot13'ed strings, which isn't,
erm, too challenging. Anything else? I've only looked quickly at it during a
train ride.
