Allright, here some cheat codes that I had been used:
1. UP0- Upgrade nothing , UP1- upgrade to lv. 1, UP2- upgrade to lv2, UP3- upgrade to lv3
2. These codes 'OUTMYWAY' and 'RESETYA' can be activated by pressing H button (horn).
3. After you finish all the tournament (except the last tournament) you can use the cheat codes by clicking the cheat code view button.
You are not allowed to request a sticky.
