Just yesterday an unofficial port of Honeycomb was made available on the NOOKcolor that was based on the official Google emulator and various other sources. The original developer has been hard at work and has now updated the port with some stability improvements and sound.

The update published today includes both sound and graphics improvements. You will notice smoother running of Honeycomb as well as sound output from the system. Also added is the ability to play non-HD videos from m.youtube.com and the SD card slot is now accessible allowing SD card storage.

In addition to the updates made available today expect the following to be working:

-Graphics acceleration
-Accelerometer
-Wireless
-Touchscreen
-Buttons
-Sleep/Wake
-Sound
