As the title says, I got my ps3 copy today (although I'm waiting for my xbox copy to ACTUALLY play it haha) and thought I'd try to unlock 1999 mode.After start screen just enter up, up, down, down, left, right, left, right, circle, X, start (on ps3) and a screen will pop up telling you you've unlocked it and it's available to choose from new game when selecting difficulty.
This is what the poster says. I would link it but I'm on my phone.
