You dont have to have psp to play games on this emulator

Well in a way it does since some games only look / play right with the psp fonts, and you can't legally take them off another persons psp.

I just know it's a forum/jpcsp rule and forums / software can have usage rules even if something is legal and I think its perfectly a good rule since the likely-hood of someone just borrowing a psp and buying the game is very unlikely.
if you don't like that example take Connectix Virtual Game Station, the software didn't require a psx , but sony got mad ...long story short it got shut down.
