Please help, important FF question

hey guys, i just played FFX and it was an awesome game. now, i wanna play FF7 and FF8. im trying to buy the games online but I can only find USA NTSC versions. i brought my playstation 2 and i think its a Japan NTSC version. So my question is, will the USA NTSC version work on mine?

and if it doesn't work, anyone know where i can buy these games in english which are compatiable with my PS 2?

btw, final fantasy X i played was "Final Fantasy X International"
NTSC -J

thanks in advance for any replies.

Yes, but you need to have a boot disc as just starting the games normally wont work.

ok, so can i buy the boot disk online? whats it called?

thanks in advance
