You have to register, then go to the download page, then click on Disneyfanitic name in the left hand column and that will bring you to his threads on this board. From there you can click on the links to the download page for his various Disney Fireworks. For Believe you also need to find his link to WINRAR which is a WINZIP like program you need to process this file. Read the thread as it has questions that you may be asking and he answers. If I can figure it out, anyone can. Basically you load the RAR file for Believe to your desktop, then load the WINRAR program to your desktop. Click on the WINRAR program, it will find the only RAR file which is beleive and you then extract the beleiver RAR file to your desktop. It now is an EXE file. Click on this and it will extract the visuals and place it the proper folder and also place the MP3 soundtrack to the proper folder. When you open Fireworks Mixmaster and then open the folder to load shows, you will see Believe in the listing. Drop it and set the months and time just like any other show. I put Sleeping Beauty Castle in front, lifted the land the fireworks were on up to the balcony level at the back of the castle, added some reflecting water, path and light to the front, and when the show is slated to start, click on the fireworks emblem in the drop down menu, and you will get a peep eye view of the show. There are many angles you can pick from the pop up menu at the bottom, just like Coaster Cam. The music and visuals are very well timed, only off by a little.
Fantasy in the sky produces two files that you extract to the proper folders, one for fireworks and one for music. They go in My Documents, RCT3, Fireworks folder for the visuals and music for the MP3 file.
Hope this helps. It's a little time consuming but worth the effort. You do need a Pentium IV and lots of memory and speed to run this properly.
