Lap & Speed Modifier is the name of an Mario Kart Wii extension to modify the number of laps and the basic speed of a race. It was developed by MrBean35000vr for CTGP and is also available as cheat code.



How it works (STGI)

The Lap & Speed Modifier reads some values of KMP/STGI:

  • The byte at offset 0 is used for the number of laps, if it is between 1 and 9.
  • The 2 bytes at offsets 0x0A and 0x0B are interpreted as the 2 most significant bytes of the floating point speed factor. The usual range is 0.5 to 2.0.

Cheat Codes

Cheat codes are available for 3 regions:

PAL

NTSC/USA

Wiimms SZS Tools

Patching Track Files

The values of the STGO section can be patched easily by tool wszst:

  • wszst patch --speed-mod=factor ... will change the speed factor.
  • wszst patch --kmp=3laps ... will patch the lap number. Values between 1lap and 9laps are possible.
  • wszst patch --kmp=MODE ... will patch the pole position (modes left or right) and/or the narrow mode (modes wide or narrow).

Patching main.dol to enable LS-Mod support

wstrt patch supports the option --add-section=file to add a section to file main.dol. The section can be a gecko code interpreter together with some cheat codes.
