Confidential Mission and gun compatibility problems

[Monkster]

Hi Time,

Listen my friend, was wondering if you could tell me a bit more about these guns.. Me and my friend stupidly went and brought an official gun pack at the weekend with house of the dead 2. Is It true that madcatz guns are regionless (ie does it work with NTSC confidential mission) cause I want to get one and get rid of the Dreamcast official gun I have.. Also do you know if the Thrustmaster one is also region free..??

Thanks in advance for any help on this.
