Hi, greeting from Ecuador, im have a problem, im downloaded games from the PSN, the games are full, when is a DEMO i just use the proxy server and a paused download, but when i want install a full game in the PSN just have the button Buy Now.
I'm sorry, I don't quite understand your question.
If the game is a full game then you will only have the option to buy now, since there aren't any free full games. The only free games are demos and so they will give you the option to download without buying. Sorry if I have misunderstood.
That list is for archival purposes these days, as although you can install the games with the Proxy method Sony blocked running them back in PS3 Firmware 2.36 so the only way you can play full games is if you pay for them.
