Is the backwards compatibility of a PS3 multi-region?

I know that PS3 games are region free and that I can play games from America on the PS3 I bought in the UK, but I was wondering if I bought an NTSC PS1 game, would it work on the PS3 bought in the PAL region?

Thanks.

No, it won't. PS1 and PS2 are region-locked games. You have to use a PS3 from the same region if you want to play PS1 and PS2 games.

yes it willHarshGamer

nah it wont work some ppl just say stuff from their assumptions but im talking from experience cause once i tried playing tomba2 (restoring my childhood memories yeah those good old days) well it was american region (ntsc) and my system is pal so it didnt workrey-mistyrio
