PS2 Questions
 

Qn 1 : I have a SCPH-30004 R PAL PS2. I don't know what type of modchip I am using, but all I know is that I need to push the eject button to change modes to play certain games.

Qn 2 : I have been playing PS1 NTSC games on it and found that the sound don't sync like NTSC PS1/2. Is there any soluton to it.

Qn 3 : I found that when I insert any PAL PS1 games into my PS2, it doesn't need to be swap with the AR2. Does that mean that if I convert all my NTSC games to PAL games, I don't need to use the swap trick?
