Don't laugh at me. I just now, today, got a PS3. Obviously, I'm not much into gaming anymore. But, I figured I can get a decent used PS3 now that the PS4 is out. I suppose it's too late to redeem the old DYRL side scoll game that the box set came with. I set up my Japanese account, and I entered the code, but no such luck. I'm assuming it's telling me the code is no longer valid or something, but since I can't read Japanese don't really know what it's telling. I tried redeeming under my user account settings, and I tried in the PSN store as well.
I knew it was a long shot, but I had to try.
Actually, I still have the physical PS1 game that I purchased years ago, but it wouldn't play on my US PS3.
