Jap Game Boy Player and US/UK Carts

[fumi]

I am about to pick up a Jap Game Boy Player to add to my Japanese gamecube.
However I have one minor worry and that is if I can still play all my old US/UK carts on it. Is there any regoin lock-out or am I ok?

Regards

You're fine - carts from any region will run on it
