The 2.70 firmware supports the game demo run from the MS directly. I have download the LocoRoco demo http://www.jp.playstation.com/R/dl0425_locoroco just now. It should be only running on 2.7, but I change the version mark in the SFO. It can start on my 2.6 PSP but auto shutdown.

anyway,if it means we can run something on 2.6 or 2.7 just make something LIKE a demo but with our own code inside? who can anayse the LocoRoco demo and make a simple one out?
