Yes you can
Until the MP5 standard is fixed in what it will do and what it will not then you will have to be patient.
MP5
The PSVita does not support the PSP UMD games, but does support a very large percentage of digital PSP game purchases.
No, the PSP GO does not support UMDs at all. It has to download them from the PSN.
all psp support video player
yes, with a "psp emulator"
There are no such things as 'PSP 1000' games, no PSP game is made for a specific model. Any PSP UMD will work in any PSP that has a UMD drive.
the purpose of psp game is that you can experience the game by yourself :)
WWE 12 is not a PSP game and is a PS3 game and can not be played by the PSP
the game has to be game share compatible. you basically got to gameshare on your psp and then your friend loads the game up n his psp.
If its a psp game, it will run on any psp system (providing its not faulty). If its not a psp game, it wont work on the psp.
