Cheats:

 Well, they are not this easy to obtain the cheats for this game. To
 get the bonus track (Las Vegas) you'll have to win the tournament
 once. It also makes the following cheat code available:

 EAC POWR  - makes the bonus car available
 EAC WARP  - makes gameplay go faster
 EAC RALY  - turns Rusty Springs into an Egyptian dirt track

 EAC TURBO - Super turbo

 You type them in at the prompt for the player's name when starting a
 single race.

 There are also several other cheat codes that show up in the
 TNFS.EXE file:

 TEST SCAR 4X4R WACK RULE QAQA TIME SLOW

 The 300mph Porsche:

 This modification can be done with any of the cars, I have only tried
 this with the 911.

 Look for paths.dat in the /gamedata/config directory. Load it into
 a hex editor and find the line that is:

 [Drive]:\simdata\carspecs

 (Of course you have to set the cd rom drive letter for [Drive],
 mine is D)

 Now replace the letter of the cd rom with the letter of your hard
 drive (mine is C).
 Create a directory c:\simdata\carspecs. Copy all files from
 d:\simdata\carspecs to c:\simdata\carspecs and change to
 c:\simdata\carspecs.
 Change the attribute of the by_r&t file to read only (attrib +r
 by_r&t.) Copy traffc.pbs to p911.pbs. You have just created a
 300 mph Porsche.
