NFS HS Expansion Pack 4.0

Patches the game, makes it compatible with all Windows versions, and also contains everything for online play. Adds new cars and great tracks (including conversions from NFS 1,2).

Includes:

IPLounge - a chat program for playing online in HS and PU
Official patch 4.5
High poly patch
New 3D Setup
3Dfx Glide
Patch for all OS (Vista, 7, XP, 2000, Linux)
Patch for multi-core processors
Fixes for all problems (1 MB, menu, etc.)
Adding the game to firewall exceptions
Enabling intro movies
Unlocking all tracks and cars
Fast cops
New cars and tracks (pre-installed sets, ability to add your own)
Service center (HS Mixer) for quickly switching between the standard and upgraded version
How to install: Run the installer and select the desired options. Install only on a clean game! It is also important that it is registered in your registry, since the installer finds the folder itself. Therefore, it is better to install a full original version rather than one from compilations.

Some nuances:

Default installation is recommended + the patches you need for Windows and processors, as well as 3Dfx
For online play, check: IPLounge 4.08
To view intro movies: Enable Movies
To play in 3Dfx mode: nGlide (recommended) in the Glide Wrapper menu (after installation, configure it via the Start menu)
Faster cops: the Hot Pursuit Cars Add-on item
