Hi there BT. Actually, there is a simple 2 part process to getting .zip files into your game. First, you have to get the .ztd file contained in the .zip file. ZT1 only reads .ztd. If you download it from here, it will be in .zip format. You will need winzip, so open the .zip file with that. Inside should be the .ztd file. This file will need to be moved to your update or dlupdate folder. Once you do that, the download should be available in your game. Thanks!
