Its NTSC but for PS3 its no longer a problem coz ¨Pal game work on it not like the case of PS2
Only your TV must support NTSC/PAL and most TV'S does.
You can do your research to be sure.
And ¨PS2 games will not work on it , only PS1 games as I read in the manuel.
so if you got PS3 console why you look to play on it old games of ¨PS2
