I'm currently using Myth's GTA3 v1.1 No-CD crack. It works fine. Just be sure to download the patch that converts GTA 3 to version 1.1 from 1.0 from Take2's support page first. Here's the link to the patch site:
http://www.take2games.com/index.php?...ection=patches
Just follow the directions once you've downloaded the patch.
If you're having a graphical problem and you run WinXP, it could be a problem with your DirectX 8.1. Take2 also has a fix file for that. Just look for it under Support.
Post back if this helped.
