Ps3 – play night or community operations in PS3

1) Not to my knowledge as it currently stands unless the game ALSO states its playable on the PS3

2) I assume you want to hook the PSP up to the PS3 to play the PSP game on the PS3 with the PS3 controller, This is also a No (You can remote in to a PS3 and play games on the PS3 that stream to your PSP... But I so far only have done this with games I have purchased digitally like Wild Arms 3)

3) The Slim PSPs (rev 2000, 3000) have a cable you can buy that allows you to play the games on a TV (Go search Amazon.com and Id suggest the Sony cables).

Some PlayStation 3 games have locked game-saves which means their game-saves are tied to the system itself. The result is that if you backup these files in a USB or an external HDD, you won't be able to use them in another system. (This is most likely done through encryption).

Here's a list of games with locked game-saves. As the list states, games without asterisks have files which are locked to the system.

However, there's a way to bring these locked game-save to another system. The PlayStation Plus service lets you upload these files to Sony's servers to be able to retrieve them in other systems. This service is not free.
