TOCA TOURING CAR CHAMPIONSHIP  

Enter the following cheats when asked to enter the players name. Tiff
should say 'cheat mode enabled' to indicate that the cheat is active. 
To disable a cheat simply re-enter it in the player name field.

CMGARAGE - enables the elusive extra two cars, the first is a tank, 
which
has a gun instead of a horn, thus allowing you to, quite literally, 
blow
the opposition away. The second is a pink caddilac (I think!)

CMNOHITS - Turns off collision detection for ALL cars on the track.

CMSTARS - Starry sky that replaces the 'normal' sky and weather.

XBOOSTME - Speeds up the game

CMCOPTER - Views from the Helicopters that hover above the tracks 
(not real useful though)

CMMICRO - Overhead view of the track. NOTE: This replaces the 'behind 
car (far)' view.

CMCHUN - First person view with just a steering wheel and hands (a 
bit like being on a kart)

CMDISCO - bright lights in sky pulsating to rave music (wierd when
combined with CMCHUN + some magic mushrooms maybe)

CMMAYHEM - vicious opposition who will even slam on the brakes

CMTOON - cartoon horizon

CMDISCO - disco fog

CMLOGRAV - low gravity (affects cones)

CMRAINUP - rain falls upwards

JHAMMO - all tracks!!!

CMLOCK - locks tracks

FLEXMOBILE - pink car

There are some others which are just fluff. I notice that Chun is one 
of the coders, and it maybe worth trying some CM... other coders names.

Winning the championship with all the gold medals doesn't give 
anything other than the mirror-track championship and lava land track. The
sequence is still the parade truck and credits.
