Okay, first of all, there aren't any trainers or hex editors for Timescape: Journey to Pompeii.
Adrian has no stats, skills, hit points, or other traits you might conceivably want to edit.
One hit from anything, including a punch in a brawl, automatically kills him and you'll have to reload.
There's nothing you can do to change that. So there's not much cheat to be had in this game,
but if you need a puzzle solution or just want to learn more about this game, here are a few good links for you:
Universal Hints System is a great place to get a hint for one specific puzzle you're stuck on without accidentally ruining the rest of the game--they have
a walkthrough uniquely structured to reveal only one hint at a time.
TimeScape's developer Cryo Interactive has gone out of business, but the publisher The Adventure Game Company is still supporting this game, and their tech support is generally helpful.
Here's another Journey to Pompeii walkthrough site, this one with explicit travel directions. If you're lost and can't find your way out of the street you're stuck in, this is a good place to go.
The rest of these links aren't related to Timescape: Journey to Pompeii, but you may enjoy them anyway... most of them were created by me or by friends of mine. (-:
