so i finally managed to pull out House of the Dead 2 and give this thing a shot. to my surprise, it's region locked. boot up game, and it gives me

"peripheral at port a is not supported in north america"

is there any way to determine if this is japan or europe based? and is there any possible way to get around the region lock?

the side of the gun says

"Sega HKT-7800
Sega Enterprises, LTD.
Made In Japan"

past that, no other information on the gun.
