Hi Ka-Ho,
In reponse to 'how is PSP compatible with SingStar?' it is all linked to remote play. For licensing reasons you cannot take your SingStar video's with you via your PSP however you can access the SingStore when you are on the go:
SingStar includes Remote Play functionalities with PSP. Using PSP and a wireless Internet connection, players will be able to access various areas of the game such as:
SingStore: browse, select and download new songs, from SingStore remotely. This is really your chance to get your favourite party tracklist ready before you’re heading back home!
My SingStar Online: browse and participate in all areas, rate media, leave comments, take part in polls, etc.). You can now continue to be part of the SingStar community on the go: share and show off hilarious and killer performances to your friends and family!
If you have any more questions please ask,
Love SingStar Team
