How do you game share on socom navy seals fireteam bravo 2

You are probably misleaded by the Socom 2 'game sharing' idea. Sony cheaped us out by only sending a demo when you game share Socom 2. So that means you can't play your friend one on one unless he gets a copy as well.
If your still interest in giving your friend the 'demo'. You need to run the game and go to options and find the game sharing icon. Click on it while your friend is in XMB mode on his psp, where he can still move around selecting icons. He needs to select the game sharing icon in the XMB and accept your request to send the demo. After that it should send and save to his memory stick.
I hope that clarified your question.
