i tried the method explained in post 8 and it's working good.
the bad news is that I tried to install METAL GEAR ONLINE, and when it's installed, I try to make it start and says "Copyright Violation when attempting to install game" error 80029513
Some demos like MGO, Def Jam, MX vs ATV, NHL 08, Lair and Echochrome require activation from the PSN store. So you have to download them from the PSN store using the real URL. In this case the method explained in the post #8 will not work with these games, unless you activate the game first.
Anyway the METAL GEAR ONLINE public trial has ended.
I try install a PKG that does not correspond with the download link, using the steps in post #8 ... and ... error. all steps are correct, second download in background paused at 32kB, but... will be waiting other method
...sorry, i don`t read this thread to end, i`m trying to install NHL08 - what don`t working by this method...
If you go to the Playstation store and download a demo and click download in the background and then download another demo and click download in background (click the download in the background button really fast!)
Then go to your download management screen and pause the second download and then the first one. Now replace the second downloads url in ps3proxy and resume its download. It should download the demo or whatever you what in that games place. Install it like normal then restart your ps3, and run ok.
