In the PSP in which folder do you put the games?

You will have to hack your psp ( Cracking ) That depends on which version psp you are having and what motherboard you have and you must check that your motherboard is crackable. it is very dangerous to do it so give it in the shops in which they crack PSPs. After cracking ( After putting a firmware ) your psp will have more folders ( ISO,Seplugins and more) So you have to put the games in The ISO Folder. The Game formats are ISO and CSO. Don't crack by yourself. But if you have experience in Cracking, Then do it...
