MKWii Item Rain install guide (gecko code)
Introduction
Read my cross-posted reddit post here.
Luigi targets bullets and stars as items fall in Bowser's castle
Want to play Item Rain without CTGP, on Dolphin, or without your disk? This guide will explain how to get Item Rain using Gecko codes. Gecko codes can be used for other mods and cheats as well.
All of the codes below are for NTSC-U (North American version) but you can follow similar steps for other regions and I can help if you leave a comment. I’m using the version of Item Rain which drops bullet bills, stars, shocks, etc. along with the regular items.
Dolphin Steps:
- Enable cheats in Config -> General -> Basic Settings
- Right click Mario Kart -> Properties -> Gecko Codes
- Add the codes below
- Play the game
USB Loader GX Steps:
- Create a “RMCE01.gct” file using https://mariokartwii.com/gct/ and the codes below. The game ID is RMCE01 (for NTSC-U) and add the codes below before downloading the GCT file.
- Place it at /codes/RMCE01.gct in your Wii’s SD card. (/codes/RMCE01.gct is the file path in the SD card, so make a folder called codes.)
- In USB Loader GX (or whatever you’re using) turn on Ocarina and make sure it’s enabled for Mario Kart Wii.
- Now Item Rain should be enabled in every game. Turn off Ocarina or remove the gct file to turn Item Rain off.
- Your game may crash. Mine does occasionally. Hold the Wii’s power button to restart :(
Gecko Codes:
- I will paste my Gecko codes below and explain where I got them after.
- These codes only work on NTSC-U (North American version). For other regions, follow my explanations for your region. If there is interest in comments, I may help out
- All codes are required except for “No Item Boxes” as is explained below
- Any readable text is not part of the gecko codes, including the names/titles

Codes explanations:
Item Rain:
- Source: https://mariokartwii.com/showthread.php?tid=1456
- I filled in XXXXXXXX, YYYYYYYY, and ZZZZZZZZ using the values that the author suggests on page 4. (X = 3F400000, Y = 42480000, Z = 44BB8000)
- I removed the last 2 lines which prevents a crash when used with “Disable Item Poof” (important), and I move the lines to “Good Item Limiter” where I use different values which crash less.
Disable Item Poof:
- Source: https://mariokartwii.com/showthread.php?tid=1716
- Without this code, items will disappear off the ground after a very short period of time. IDK what CLF78 did, but it’s good. Feel free to test without it.
All Items Can Land v2:
This code lets every item (except the Thundercloud) land on the floor when dropped. They will activate when a racer drives over them, and their effects will be identical to if the user actually fired the item themselves.
- Without this code, the OP items (bullets, mega mushrooms, etc.) will disappear instantly. Goated code.
Good Item Limits:
- Source: https://mariokartwii.com/showthread.php?tid=405
- Changes how many of each good item can exist at one time. This is meant to allow more to be on the ground at once. I tweaked these but you can change them if you wish. Having more items means it’s more likely for the game to crash or bug out. The numbers are the second half of each line.

No item boxes:
- Source: https://mariokartwii.com/showthread.php?tid=169
- Doesn’t 100% work on some tracks (like Toad’s Factory)
- I removed item boxes because I think boxes make the game crash more. Test it yourself if you’d like.
