I bought Resident Evil 2 off of Amazon.com and I recieved it today. I bought the original black label version. When I opened the case the discs were two different colors so I put disc 1 in and it was the dual shock version; I then put disc 2 in and it was the original. If I play to the end of disc 1 will disc 2 work with still work with disc 1 properlly even though disc 1 is dual shock version?
