Hey Nerds, these are codes I found in the ROM files of the N64 version of Polaris SnoCross and the ISO of the PS1 version!
They are not Gameshark codes but can be inputted through the ingame menu and have not been posted anywhere on the internet before to my knowledge. I scoured the internet for these codes but because I had to actually go into the game files I am 99% certain this is all of them.
To get to the code input menu
From the main menu select OPTIONS
Then select SAVE/LOAD
Then select ENTER CODE
The codes are as follows:
Give 100 Wrenches to All Unlocked Sleds Ckp041980
Unlock Semi-Pro Sleds Bcd101261
Unlock Pro Sleds Gvb081376
Unlock 600 Edge X Sled Kb7r51075
Unlock Sno-Razor Sled Bdk041473
Unlock Lobster Kvv121766
Unlock All Tracks in Single Event Bks070971
If you input a code then save your game to the memory pack it will have that content every time you load. This means that you can access the end game content needed to speedrun time trials or championship mode without grinding through the game naturally if you desire. Unfortunately, these codes only unlock the tracks in Single Event and not the championship mode.
IT ALSO MEANS SHREDDING SOME WICKED POWDA ON THE LOBSTA!!
