This is my Raspberry Pi Portable. It has a overclockable 700mhz ARMv6 processor with a GPU equivalent to the first gen xbox, it runs a derivative of Debian Linux called Raspbian (get it?) and it can emulate pretty much anything that came out before the GBA (2001)
it has a 5" HDMI screen and a 3600MAH battery which gives it a life of about 2-3 hours running full blast.
it also plays doom with cross platform multiplayer support via chocolate doom,and it also plays classic RTCW, albeit it runs 25-45 fps and there is currently no multiplayer support although a few people have compiled ET to run for the hell of it, but I think it isn't compatible with the PC version (yet!)
the project is still not complete after a year of work but I have hit the brick wall of not enough money, if you would like to donate to this aspiring young hardware engineer then please send your money to TSE, because he will probably confiscate it all anyway.....
