thanks

this is easy…
first of all, download a bittorent programme…
“BitTorent” search that on google and download it..
then u search whatever games u want.. eg
“nba live 09 psp game bittorent download”
and just slowly find it.. you will get to find it somehow
but it is illegal as u know

bittorrent takes long to download and its illegal to dowmload full version game of psp….
try this site

There doesn’t exist any free download site.
