How do you know if a game supports the trophy system?

May be...

For example, I have MGS4.

How do I know if it supports the trophy system or not?

The trophy system that shows the trophies I have on my PSN.

Games that support trophies will show up in the Trophy Collection found in the Game XMB Category.



I'm pretty sure all new PS3 games are required to support the trophy system. MGS4 was released before the Trophy System was added on. These older games had the option whether or not to make a patch that supported trophies. It was not done for MGS4 and is not likely to happen.

like sarcastic joker said all PS3 games now need the mandatory trophies since 2009
