== Source code ==

B&N's [[http://www.barnesandnoble.com/u/Terms-of-Service-NOOK-Color/379003278|legal page]] has source code for the Nook Color (see "Third Party Software Terms").

== Phone UI ==

To tell Ice Cream Sandwich (Android 4.0) to use the phone UI, create /data/local.prop, and add:

{{{
qemu.sf.lcd_density=240
qemu.hw.mainkeys=0
}}}

The first line sets the DPI; the second enables the soft navigation bar.

== Switching to Helvetica ==

Download [[http://forum.xda-developers.com/showthread.php?t=874658|Font Changer Lite]], and install HelveticaNeue as new default (replacement for Roboto) font.

For Firefox, set:

 * font.name.sans-serif.x-unicode
 * font.name.sans-serif.x-western

to "HelveticaNeue", and set:

 * font.name-list.sans-serf.x-unicode
 * font.name-list.sans-serf.x-western

to "HelveticaNeue, Roboto, Droid Sans". Also set:

 * font.minimum-size.x-unicode
 * font.minimum-size.x-western

to "14" (or appropriate).

== Dissecting a uRamdisk ==

In update packages, ramdisk.img is renamed to /boot/uRamdisk.

{{{#!highlight sh
# Skip 64-byte header
dd if=ramdisk.img bs=64 skip=1 of=ramdisk.gz
# Uncompress
gunzip ramdisk.gz
# Extract
mkdir ramdisk
cd ramdisk
cpio -iv < ../ramdisk
}}}

Once modifications are made, you can recreate the image:

{{{#!highlight sh
find . -regex "./.*"| cpio -ov -H newc | gzip > ../ramdisk.gz
mkimage -A ARM -T RAMDisk -n Image -d ../ramdisk.gz ../uRamdisk
}}}
