1. If I have a PS2 US serial # U5, 30001 Do I have to use GameShark2 or can I use REGION X?

2. If I get a GameShark2 is the Version 1.6 good or will it work on my ps2?

3. Does REGION X have codes capability?

4. Is REGION X and GameShark2 like the Action replay for PS1. Like for mod protected games you just enter a code and it can play?

5. If the GameShark2 or REGION X dont work could I return them?
