Do the puzzles in Silent Hill 2 for the PS3 have fixed solutions? I'm asking this because each and every time i've played the game in Normal, Hard and Extra Riddle Difficulty the solutions are always the same, like:

In the afe puzzle the solution is always 16 >> 09 << 04 >> 16

In the carbon paper is always 9598 The blood wall is always 2421

And the suitcase is always LOCK

The same happens with the bug room and the hangman in which the innocent man's body is always on the same position.

Is it just me or does the PS3 version indeed has fixed solutions???
