Boring, no really interesting news around so I'll try to keep you interested with this little discovery. Tested and working on a retail PS3 machine.
Not only the lame PS3 Internet browser is able to play flash files, the music application Vidzone is also.
Here is a little example:
The startup Vidzone logo and the main menu layout are simple .swf flash files. Write your own flash file format 5 and simply replace those two files to run it standalone by starting Vidzone:
First replace: /dev_hdd0/game/NPEA00135/USRDIR/VidzoneChannel.swf
Second replace: /dev_hdd0/game/NPEA00135/USRDIR/HDForms.swf
I won't explain how to replace files on HDD again, you should know that by now. I'm still experimenting so find out what is possible yourself in the first time.
