The box in the bottom right is the mode, (either Any% or 100%) the box in the bottom left is the split timer, and the box above that is the main timer (It updates when you reach the moon requirement or certain events in Bowser's Castle)
Thanks to DuckGoose9254 for the OG project. Versions: V1.0 : 12/28/21 - The project was published V1.1 : 3/10/22 - Changed the split timer from the default timer to a variable so it can account for lag
