I just got done proto typing an internal solderless modchip that does the following(fat only not sure of the internals on the slims):
Boot in modchip mode by pressing power, or boot into normal mode by hitting eject. In modchip mode it disconnects power to the motherboard, waits 2 seconds, then reapplies power and hits power then eject to reliably boot into modchip mode, (50 tries out of 50), while doing this it disconnects the front USB ports, and after the modchip is complete in dropping payload it reconnects front USB ports and turns the modchip into an IR to PS2 emulator(for bluray movie playing)
The last thing I am working on is a mode where you push both power and eject and it turns the first front USB port into a programming port. (trickier)
The PCB layout right now for 3 boards, 1 that goes over the capacitive sensors and another that fits over the USB port traces and the last one sits outside the console on the front (fed through a small vent hole) for the IR sensor.
So, my question is, what would be the interest in this? Are there any other features I am missing?
Also since the chip is always powered, there is the possibility for an IR code to turn on the console.
Would anyone be interested in serial control? (for fancy remotes RTI,Control4, AMX Crestron, ETC)
