Attention, il est possible que l'application ne marche plus si Sony rajoute des protections sur le PSN.
Indiquez le numéro de version actuel de votre PS3 et le numéro de la dernière version du firmware PS3 sorti, puis faites start.
Ensuite sur la PS3 configurer internet pour mettre votre adresse IP de l'ordinateur sur le port 8080 en tant que proxy (faites ipconfig en ligne de commandes et repérez une IP du type 192.168.0.1).
Possible errors
On PC:
If you get an error about mswinsck.ocx being missing, either run the proxy app as administrator or copy the included .ocx file (in \ocx) to \windows\system32. (or if you prefer, download and install the microsoft VB6 runtimes which include this required file but also a large number of other not required files...)
MS VB6 Runtime KB article link: http://support.microsoft.com/kb/290887
On PS3:
Error 8071053D - You are not running the proxy or the IP/Port are wrong.
Update request - You have not setup the proxy on PS3 side or Sony have worked around this workaround
