HARDER/SOFTER SUSPENSION, all players
812A9600 C???

This makes traction as bad as snow... or worse. It ignores your tire selection.

Example: 000A is 10 racers in Championship. You start in 10th place and cannot fall below 10th. The D0316387 activator code ensures this runs only in Championship mode.
NUMBER OF LAPS

Enter the hex value of the number of laps you want. This seems to work in all game modes. 1 Lap = 0001. 10 Laps = 000A. 20 Laps = 0014.

Very cool!

dam i have this game saving these and will you do anymore n64 hacks?

[@SpaceMeatpod]

Yes I want to return to creating more codes for other games; I've been wrapped up in other projects. I spent a long time trying to get a particular code I wanted in Goldeneye to work but it proved to be too difficult to figure out. The gamehacking website has a lot of old codes listed, although a lot of them are poorly organized and not thoroughly tested.
