Oh, the 331 I know about that one, it's 250uA in normal mode. no real
power saving there, I was hoping you were referring to a newer model

Nice. http://www.xiltendo.com I wonder why I bought the expensive original
Xilinx platform cable :-)

Yes, the concept is the same for many game consoles. Some time ago I've
started the Lua Player project for the PSP and the security for the very
first PSPs was nearly no security at all, which made it easy to just copy
the programs to the memory stick with the integrated USB port from a PC.

You are right, I think there is no cheaper development kit for this price
with audio IO, two color screens, where one is a touch screen, USB, WLAN,
two CPUs, integrated rechargeable battery etc. Maybe I'll try to do some
stuff for it when I have more time. Too bad that Nintendo locked it, so you
have to hack it.

Nice, documented very well too, take note of the errata though. Anyone
know why the analog only device takes more power then the digital? I
can't figure that out.
