It contains the original launcher as expected (at start, you have the choice in the launcher), with Google Play, and busybox commands are symlinked.
Edit: here is the equivalent PhoenixCard image, customized in en_US:
Edit(2): Look at my updated firmware, fixing the CPU hog bug: http://tmerle.blogspot.fr/2012/10/melehtpc0929betav13-revised-version_22.html
Since this is an update.zip, no more PhoenixCard flashing process is needed, just a vfat formatted sdcard as a base media is sufficient.
From the archive, put on your sdcard:
- recovery.img (this is a CWM recovery image with Mele F10 recognition)
- bootloader.img (choose your flavor depending on the desired output VGA, HDMI,...)
You can edit system/build.prop in update.zip at your convenience. For example, you can setup the updated system in en_US directly.
So my customization is only a modified build.prop that you can put into update.zip (be careful to put it in system/)
Insert the SDCard in the device, install MeleTool.apk
Then launch the MeleTool.
Choose the option #4 talking about "Recovery" (wait a little so that the recovery img is written in nandg flash)
Choose the option #5 talking about "bootloader", the device will reboot after having written down in flash the nanda bootloader.
At this stage the device is stuck since it tries to boot on SD, remove SD, remove power, put power.
You should enter into CWM recovery. Insert again the SD.
Choose "apply sdcard:update.zip" (wipe data/cache before if needed)
After that, reboot and you are done.
