Hey. So, does anyone use this server to go race/hack anymore? Whenever I go online, I can't find anyone but myself. (running 2 instances of Dolphin)

Random Item From Item Box

Works everywhere. When using offline, CPUs are also effected.

This code will make all Item Probabilities exactly equal. It works for all items, any position, in any size room. This code is modifying your item probability table that is calculated from itemslot.bin.

Apply Any Position's Item Probability Values

This code will allow you to run any positional item probability values as your own regardless of what your actual position in the game is. There is one setback with this code... For example: If you set the code for 11th place items and there's only 8 players in room, then the code will not function correctly and you will get item value 0x14 non-stop. The position in room must be a valid one. To view the item probabilities for each room size of Online VS, view this page - http://mkwii.org/item/ (credits to XeR)

Selective Item Max Probability

NOTE: This code will malfunction if the room size decreases during the race.

This code maxes out the item probability of a desired item. It is NOT a shared item code.

This code is 100% undetectable if and only if you activate the code to get the item in a legitimate position. Shared item detectors cannot detect this code. Item Value 0x14 detectors cannot detect this code. The only way someone knows you are using this code is for example: You activate a Shock in 7th of a 10 player room (and its available), you get the shock. Somebody else in the room is using a version of a USB Gecko Item Spy code (which can be used on Dolphin with Aldelaro5's live RAM Viewer), and is watching everyone's items live. He/she then sees you got the shock in 7th which is an impossible position to get the shock in a 10 player room. Also doing plain jane dumb stuff such as getting 6 of the same items in a row will get you caught. Some GOD code users have been caught in the past for getting a certain item over and over and over again.

This code is much better than any version of Shared Item Codes:
If you item is not available, you get a different legit item instead (no more 'Mushroom instead' aka item 0x14).
If you are trailing/circling triple items (such as Trip reds), and you activate triple item again; you will not get the triple item. Which is correct.
If you are in a Mega, and activate a Mega, you cannot get a Mega. Which is correct.
All Timer rules are followed ofc (25 seconds POW, first 30 seconds blue, 30 seconds shock)

Greetings fellow comrades! I am 420 Matt. I have hacked MKWii for a very long time. Probably the first ever MKWii hack I used was back in 2011 where I used a bullet bill speed modifier by mdmwii to unlock everything before I knew of the ULU code. Another name I went by back when MKWii hacking was golden (2012-2014) was Matt224. I was very much involved in the MKWii community with various clans such as 4DR and WWT. (WWT was a clan I believe that was branched off of BF when some members were rebelling against one of their leaders in which I hated back then with a flaming passion) Due to unfortunate circumstances of cyberbullying, trolling, etc. I have quit the community several times, but then joined back since I had struggled to find something else to do to make me happy. I could go on and on, but that isn't necessary for this thread. Now I mainly play online on Wiimmfi, Altwfc, and now this site's server. I also am very much into the Smash Bros. and Fire Emblem game series. With all that being said, I am happy to be here as a member of mkwii.org!
