Then extract the two folders into your psp/game folder.
Now follow these steps:
1. Run MGS PW D3 fix
2. Then click circle and then you can play MGS PW without any freezing problems,
However if you want to play a DIFFERENT i repeat DIFFERENT game on your psp then you must run MGS PW NEVER otherwise no other games will work!
You must do this every time you want to play MGS PW,
