Here's a full list of the Jurassic: The Hunted version differences which should clarify why the leaderboards have been split up the way they are. The HD Version is the baseline version, but I will list the unique aspects of it as well.

- Plasma Rifle (New Game+ only)
Wii Version

Top Shot: Dinosaur Hunter is a 2010 rerelease of Jurassic: The Hunted for Wii. The version is identical to the 2009 release with the exception of a new HUD layout and a shooting gallery mode. The game also came with a Top Shot rifle accessory for the Wii Remote and Nunchuck. These two versions can be played interchangeably.
You might think that because of the shorter levels and fewer enemy types the PS2 version would be the fastest. But loading times often reach half a minute, the weapon placement means you'll have less powerful weapons during the "hold the fort" sections and the game also runs really slow and often hits framerate issues if you have more than 3 enemies alive on screen. It's by far the slowest versions.
