help!! european console + ntsc game???

[memorox]

hey, i've got a european psx (chipped). question is: will it also play 'backup versions' of games burned in north america that work on north american psx's?? i don't quite understand the whole pal/ntsc/geographic coding thing. i have a tv which will play NTSC as well as PAL, so that is not a problem. just need to know if the european *playstation* itself will play american-version games.

to any answers, opinions, or inputs (even if you're not sure).... THANKS!!!!!
