What firmware does the NXT need about nxt-python HOT 3 CLOSED

nxt-python 2.2.0 should run with any version of the original LEGO Mindstorms 
NXT firmware, since the direct commands protocol (the way your computer talks 
to the NXT via USB or Bluetooth) has never changed!

LeJOS is not supported (the firmware does react to direct commands, but 
differently than the LEGO NXT firmware).

You should just get the latest LEGO firmware from the official Mindstorms 
homepage, http://mindstorms.lego.com/en-us/support/files/default.aspx#Firmware 
. John Hansen's enhanced NXT Firmware for the programming language NXC works 
too, btw.

If you're interested in differences between LEGO firmware versions, check 
http://www.mindstorms.rwth-aachen.de/trac/wiki/FirmwareVersions .

Oh, and if you want to use the new MotorControl technology from nxt-python 
2.2.0 (you have to download MotorControl22.rxe to the brick), then you need a 
LEGO firmware 1.26 or better (again, just use the latest from LEGO homepage, 
and you'll be fine -- there is no reason to stick to an old 1.0x version).

Questions like this one are not bugs and should be posted to the mailing list, 
thanks!
