It's supposed to have 90% of PS2 games compatible from what I know.
Dunno about those specific games.
Edit: Found where you can check for a European backwards compatibility list.

It's not a complete list apparently, but I can tell you Okami and Ico both work fine according to the list. The others aren't on it.
Thanks to Blacksaber for the sig!
