This lets you score 0.0 in every Chocobo Event and Race.

Launch the trainer.exe and hit SHIFT + 1 on your keyboard during a chocobo race/training to freeze time. You will hear a single beep when its enabled. 

You may need to alt tab to get the trainer to respond
You will get 0.0 in every single race and earn the Sun Sigil on the first try.

I have included the Cheat Engine table for those who dont want to run the .exe - that requires cheat engine to work.
