I saw this and i just want to share with you.
Here is an example for you to try: http://www.ps4news.com/forums/attach...chmentid=15288
Unzip the file on the root of an usb or flash drive. Go to the device in the video menu and launch "AVCHD" it's like a mini DVD, with a BD-J game on the "BONUS" section.
This might lead to something or not who knows.. at least we have some homebrew.
Edit: Also included is an RSS Reader for the NY Times, BD-J PS3 Minimal Devkit, and others.
