The title says it all:

What is the easiest way to be able to play NTSC PS/PS2 games on my PAL PS2?

Thanks :)

swap magic

i think its getting a NTSC ps2 its the best way :P.

that or mod it but modding only will give you access ps2 games void warranty and its illegal.

Chip it. If you choose a good modchip, you can play any PS/PS2 game from any region. Plus, it's a one time modification, unlike SwapMagic which requires to use it every time you have to play the game

How do I do that?

No idea, I bought mine already chipped. You should look in the Internet for someone who does it, it's hard to do it on your own

Ok, thanks ^^
I think I´ll go with Swap Magic, even If I have to do it every time it´s easier :)

I actually own both a PAL and NTSC ps2, they're quite cheap these days, so its not as bad as you would think if there's alot of games you want. I own about 30 NTSC games, so it was worth the extra purchase.
But if you must, swap magic is you friend.

I thought modding was legal, just copying games was not, because you still have the option to pay for the NTSC games, you don't necessarily have to copy them.

SM isn´t bad, but with this, you can´t play PS1 games, and DVD9 games. Chip is better solution, if you want play all games. If modding is, or isn´t, legal, it depends on the country. In some counries, modding is legal, but not copying games. In some, even modding is illegal.

Of course, buing NTSC console is solution too.
