I am in Japan at the moment and was wondering what would be an average price for the following games.

Ghost Chaser Densei
Undercover Cops

I am assuming they are not cheap because they were exclusive to Japan
Any help would be greatly appreciated. Thanks!

Oh, if anyone has any other suggestions for Super Famicom exclusive titles, Please feel free to point them out to me lol. No RPG`s for obvious reasons

Cheers and thanks again
