Sony PSP is one of the best gaming platform, I used PSP for last 5 years and it just made my childhood better, Gaming quality is at best and you have to buy a UMD ( universal media disc) one UMD contains only one game and they are very costly like 800 ? per game so it’s costly . I purchased psp at 7999? and its really value for money. everything has a solution you can download a hack and you can hack your psp so after that you can put games on your Memory Stick pro Duo and you can download games from Internet. memory stick is costly but games are awesome although Sony accessories are costly.
