Notes
  • Course list is sourced from the Special Slot ID mapping. Selecting a track sets the KRT index to its slot value (0x00–0x1F).
  • Race/first/offroad times may be entered as mm:ss.mmm or directly in frames; if both are provided, frames take priority.
  • Mirror uses 150cc KRT time if its entry is zero in the KRT file.
  • All divisions match the game's integer math: time bonus is truncated (toward zero), other divisions use integer division.
  • The final score is clamped to the range [-50, 250].
