As far as I know, there's only two. Both are in the large double disc boxes. One is the original print, and the other is the same but with the greatest hits green bar. What I have here doesn't seem to match though. It's both discs in a slim double disc Ps1 case with no green bar. To my knowledge they only slimmed down double discs when they were re released. Do I just have a really rare variant?
i suppose someone could have taken a case for resident evil nemesis and swapped the insides but that seems unlikely.
