Unless you are talking about a pirated version of Shenmue 2, I think he'll probably need a boot disc. I know a lot of import shops were also selling Shenmue 2 with a boot disc bundle when it first came out. There aren't a lot of PAL games that work on both machines without modding or a boot disc, the only ones I can think of that do are Soul Calibour, and MSR because they have an option to run at different modes. I'm pretty sure SHenmue 2 doesn't have that from what I remember.
