I would recommend Ultimate Ride Disney Coaster. You don't need the CD itself to run it either although you do need it to install it.
As for the pictures, there aren't changes to the game itself, but to the mods of the games as the mods has issues like buggy mods or icons. And my goal is to resolve issues. The mods can be found within Princess_G archive floating around in some places. I have some mods that are exclusive as I have made these mods, and some of them aren't in Princess_G archive either. There's ~150 Environment mods, ~60 Themes mod, ~30 tracks. And that only means that there are only 6 known lost mods that probably will never be recovered, but at least 5 have some foundations to work with. Dark Ride Environment is the biggest lost mod as it has no foundation to work with.
Here's the list of known lost mods:
Dark Ride Environment (The most interesting thing to find. No video/pictures exist on what this is)
Lonely Goatherd (No info exists on what this could be. From a google search, it seems feasible to have it as a theme with a mountain modeled as a environment).
Aztec Theme (Only partly found, not as a theme itself. Mostly recoverable because of X’ian, and Backdrop 2 Theme which are both found, but it would not be the same.)
Terminator Environment (No video/pictures exist on what this is. However, a new Terminator Environment could replace this one.)
Cage Environment (No video/pictures exist on what this is, but it’s likely made by Layton and therefore, might be simple to recreate)
Alice’s Horror Theme (Can technically be remade. No information other than a picture via Internet Archive. Most information are lost.)
You can see why 5 of them at least have some foundation to work with although Cage Environment is questionable because it is unknown who made it, but still very much likely a simple texture replacement to resemble cage. 4 of them are based on existing concepts, and therefore new versions can be made.
Here is a example of a exclusive environment and theme that aren't found anywhere, but my local computer:
This environment is named Cadrestial Desert.
Other exclusive mods I have are:
1. Greenarian Mountain
2. Milky Way
3. Voxel Sphere
That's about it.
