Introduction:
This mod allows the wheels of the car that you are driving to hover, similar in effect to the SEAWAYS cheat but also working when not on water. Type "HOVER" to toggle the effect on or off. The angle of rotation of the wheels can be modified through SEHover.dat, a plain text file. The single number in that file represents the wheels' rotation in degrees for both the SEAWAYS and HOVER cheats. If HOVER and COMEFLYWITHME are both on, you can fly your car like an airplane. This mod utilizes CLEO Library for Vice City.

Installation:
* Download the mod (click the Download Mod button).
* Download CLEO for Vice City at http://cleo.li/.
* From the CLEO download, copy VC.CLEO.asi into Vice City's folder.
* If CLEO.asi already exists in the folder, you must delete that file.
* From this mod download, place the CLEO folder containing SEHover.cs and SEHover.dat into Vice City's folder.
This mod has been tested only on VC v.1.00 US.
