If they are games on umd discs, chances are, they will always be slow. If they are unusually slow then clean the disc. If they are downloaded it could be:
1. something slowing your psp down
2. Memory stick duo instead of pro duo
3. More advaced problems...
you will bring it in the shop and fix it
your psp cant read games just clean the game that doesn't work then take't to gamestop
Your PSP is probably running slow due to low memory. Try clearing up some space by deleting unused files.
I'm not sure they can fix our psp
sell it and buy a new one
take it to any game store and have them fix it
Your PSP is probably freezing due to old age. As consoles get older the hard drives inside of them begin to slow down and run less effectively.
Bring your PSP to a game store (like Gamestop) and ask them to fix it.
You can store the games for the PSP but can not play PSP games on the PS3

delete the data and puted in your psp
for psp go games you have to download them there is no UMD slot for the games so you cant play psp go games on a psp 3000 unless your psp 3000 is chipped.
