Monster Hunter Portable 3rd

the original is playable but you need the decrypted data,this can be done with your psp or with a version of jpcsp unfortunatelly i dont know wich version is so you will need to try.
Regarding the hd if you have problems maybe you need a better gpu because you need a medium to high end gpu on some games,ppsspp works fine even on a 1 ghz dual core cpu but you need a powerfull gpu to play higher quality games and to play the monster hunter 3 portable hd you need at least a 1 gb gpu to play properlly
