see that's what i got stuck at... I have gotten on friends computers remotely using opened ports but that was a while back and i had access to all their files and everything but i'm not sure anymore about that stuff usually you would use an open port or have them download a picture that had an attached backdoor which gave me like a port in the 8000s that was open like a Trojan and would allow you in through that... it was the old Instant Messaging days... where it was cool to know your friends password... There are alot of programs out now that will send backdoors... maybe someone could implement it into the PSP form and open a port
