Need for Speed Carbon Hex Editing Guide

Here is some information which should help you hex-edit your savegame or memory, of course not every detail is covered. If you aren't yet familiar with hex-editing you might want to read the MW Hex-Editing Guide & Tutorial, which is for MW though but also gives you some basic ideas about hex-editing a savegame. If you have any questions, comments, or concerns, please make a post here. One of our resident hex editors will try to answer your question as soon as possible.

And don't forget:
Before messing with savegames, always make a backup copy!
