so, i got myself a psp yesterday from my work for a tenner. what the hell do i do with it to make the most out of it? e.g do i need a memory stick to make full use of it? as i dont have one of those yet, and what is the best size to go for? i dont want to know about any hacks. but, what version of software do you guys reccomend i should upgrade/downgrade to to get the most out of this machine? oh, and what game should i get? Cheers
