I keep getting only the silver file when I open the safe in the first elevator escape room. I haven't changed the difficulty. I don't even know how to change it, so if it's on Easy I have no idea why it is because I didn't switch to Easy at any point. Yet I only seem to get the silver file from the safe.. Am I missing something here? I found all 3 memory cards before opening the safe, if that makes a difference. I think I accidentally got a card by hitting 0 on the elevator number pad. I dunno why that gave me a card but it did.
I can see the difficulty level in the pop-up menu, but I dunno if it's set to Hard or Easy. Easy is yellow and Hard is black. I'm sure it said that you start the rooms on Hard by default, and like I said, I didn't change anything or ask for too many hints or whatever. How do I get the gold file then?
