It depends on what you mean with "overseas" as there are different games out for PAL and NTSC regions...
There's a list here somewhere. I'll help you search tomorrow if you haven't found it by then.
Also, don't forget the PS2 is fully backwards compatible so you can also play all the PS1 adventures (e.g. most of the Cryo adventures)
