working bootloader ! Some games and samples included. To use it, decompress to a SD card , start bootloader (boot+user button) and select .bin files (except 1st and 2nd_boot of course).

The 1st boot can be used to restore the first bootloader ( see this tutorial )
The 2nd boot and bitbox.pbm files have to be located on the SD card root folder for the boot loader.

The movie file is used when trying the video demo, please add it to your SD card root directory in that case.
