So a few days before this bundle was announced I bought the Prima Guides for both DIno crisis 1 and 2. Does anyone know if the guide will work for the first game? I know there is a normal mode and arrange mode but I won't be able to test it out until the weekend. I am assuming the arrange mode is the one that will be what the guide is for but I wanted to check before I get too far into the game for a reset.

They should work for their respective game. Just remember that, at least in DC1, Arrange Mode is THE US version; while Original mode is THE JAPANESE version. Thus as you have the English guide, it is safe to assume the guide only is accurate for Arrange Mode.
