House of the Dead on Saturn is expensive for the US Release, but not so much for the Japanese. I have a Action Replay 4m Auto key thing, which I have successfully used on my import Christmas NiGHTS; thus, I know the software won't be a problem.
However, will it work with the US Gun peripheral? I would think they'd be the same, but I dunno. I actually realized (thanks to someone else's post today) what the other plug on my 3rd party PSX gun was for -- it's a Saturn plug. I, having never owned a Saturn until recently, didn't have a clue years ago.
So, in that case, will my 3rd party gun work? If not, will the US gun work? Will a Japanese saturn gun, if it's necessary to buy one, work on the US console for a Japan import of House of the Dead?
