Hi, i read something and i'm just curious.. We can write our own homebrew for psp and got it signed since we have full control of it
then we could port it to the ps3 because we are able to do so in every (official) firmware and it should run, assuming the ps3 thinks this is an orignial psp game or stuff.

Couldn't we write stuff on psp and got it workin' in ps3 without the keys? I mean, in some way, the ofw should have stored the psp keys or something to make psp games work properly?
