Silent Hill 2

[Pootle]

On Silent Hill 2 for the PS2, how do I open the safe? Is it with the code found in the wallet? Seems too easy to me, if it is and I've tried all combinations but the damn thing won't open. I don't want to consult a walkthrough guide, but this is really annoying me!

Grab the wallet from the toilet.  On it is a random
number (normal) or set of symbols (hard).  The symbols are roman numerals; V is five, X is ten.  To get the combination, add the roman numerals and any other numbers in each set.  So,

VV5 >> 6 << X5 >> XX would translate to
5+5+5 (15) >> 6 << 10+5 (15) >> 20

Turn the dial left to the first number, right to the second, left
to the third, and right to the fourth.
