Firstly, you want to download TTD. It's basically a more advanced TTO version, so it's quite simple to learn if you've played TTO. You can get it here.
Now that you have TTD extracted into a folder, you'll need to get TTD Patch(here after referred to as TTDP). It adds many great, new features to TTD. You can download the latest version from here.
OK, you've got TTD and TTDP installed, but what about those games you've been spending so much time working on. They won't load by themselves. That's where the SVX Converter comes in. It allows you to select one of your games, and convert it into a fully TTDP-compatible game. You can get the file from here.
Now that you've got TTDP set up, and your games converted, it's time for you to lay back and enjoy your newly set-up game. Have Fun
