[Sprite_TM] was given a Kodak ZX3 to play with by a forum he moderates. The Kodak ZX3 is a waterproof HD camcorder in a cell phone / mp3 player form factor. After opening up the camcorder, he did some poking around with a scope and was able to locate a serial port on the board. It quickly became apparent that the system uses a proprietary kernel called PrKernelV4 rather than an open source alternative. Not letting the proprietary kernel get him down, he exploited the system by simply modifying a file called “autoexec.ash” on the sd card. He now has a Tetris clone easily launched from a previously unused menu icon. See it in action after the break.
