hello fellow softmodders
you have a few options for these
1.) edit the uxe fonts, though this is probably too complex.
2.) run pbl-metoo and a hacked bios, you can edit the bios to change the fan speed and LED color, to do this just replace the included nkpatcher with pbl metoo.
3.) wait for an updated version of nkpatcher - rmenhal has just told me that he will add these two options into the next version of nkpatcher in the near future.
4.) change it through your dashboard - ones i recommend are avaluanch, unleashx and xbox media center (my personal favourite)
your xbox version is irrelevant my friend.
