Random Character but w/ Best Bike For Every Race Online [Vega]

Online only. Does NOT work in battle.

A slight mod to my original random character+combo code HERE to suit users who want to race more competitively. You will get a random character to race as (except Mii) for every online race (except Battle), but you will always use the best bike for w/e weight class of character you get. This means if you get a random lightweight, you are using bullet bike. If you get a random middleweight, you will be using machbike. And you will use flame runner for the random heavyweight chracter.

NOTE: This code makes use of memory address 0x800004C0. Make sure no other codes in your GCT/Cheat-Manager are using that address.

but i have to "load them twice" by loading them with Gecko using the Homebrew channel then go back to the Wii menu after the game has startet and then load them again the same way. I don't get them to work in any other way. I'm using a German Mario Kart Wii disc on a PAL Wii. These two codes don't work on Dolphin emulator at all and I don't know of any other code with this strange behavior. Does someone knows why this happens or how to fix the codes?

Random Character+Vehicle Combo For Every Race -Online- [Vega]

Works for Online only. Doesn't work in battle.

This code will give you a completely random character+Vehicle combo for each race you do Online. There's no telling what character+vehicle combo you will be when the race begins! Have fun.

This code will NEVER give you the Mii as a character to use, and your chosen drift/transmission mode is NEVER effected.

NOTE: This code makes use of memory addresses 0x800004C0 and 0x800004C1. Make sure no other codes in your GCT/Cheat-Manager are using those addresses!

Auto Attempt to Use Dodge Item When Shocked -Online- [Vega]

Outdated by Unnamed's version which works 100% reliably.

Online only.

If you are holding a Mega, Star, or Bullet Bill when the shock occurs, you will automatically attempt to use your item and dodge the shock. Whether or not you dodge the shock depends a lot on the natneg between the clients.

Non-stable natneg between the clients will most likely cause a missed dodge, therefore I wouldn't call this code reliable enough to depend on as a way to always dodge shocks. Also for any moments where you normally can't use an item (i.e. during exit of cannon, spinning from getting hit by an item, etc), the code also won't work.

If desired, you can actually edit this code to effect other items instead of the 3 default ones. The compiled lines of "2C0C0009, 000B, and 000F" are the checks for Mega, Star, and Bill.

NOTE: This code makes use of memory addresses 0x80000298 thru 0x8000029A. Make sure no other codes in your GCT/Cheat-Manager are using those addresses!

When the game firsts boots (Use boot to pause in Dolphin), at address 0x80003114 (and a few others right after it) contain the hex word "DEADBEEF".

I understand this is a weird developer's thing to use this for guides, placeholder text, and ofc easter eggs. I figured they probably inserted this in for the heck of it lol.

This tutorial assumes you are familiar with creating an LE-CODE based distribution (Tutorial on this soon) and using Wiimm's Tools, have a pre-compiled lecode*.bin, and have my LE-CODE based code extender here: https://mkwii.com/showthread.php?tid=1403

LE-CODE Code List Extender [JoshuaMK]

A tutorial for how to use this code can be found here: https://mkwii.com/showthread.php?tid=1406

This code is designed to be injected into the main.dol using wstrt PATCH main.dol --add-section NAME.gct --add-lecode --DEST ./lecode/main.dol -o, although it can be properly run in the dolphin codehandler (Not Riivolution's nor Gecko OS's due to differing instructions).

When run, this code constantly checks for the file header of the lecode.bin file (LECT), and when found, it grabs the file's size from the file header, adds it to the base address of 0x808DD400 to reach the end of the file. It then does a check for the existence of the F0000000 00000000 found at the end of a gct, and if found, loops backwards in the file until it finds 00DEC0DE 00DEC0DE, in which it stores the new pointer address at 0x80002FFC. Then it finally modifies the codehandler to load the pointer address as the start of the code list instead of the static styled (lis, ori) method it normally uses.

Enable All Tracks in LE-CODE TTs [JoshuaMK]

Normally, LE-CODE distributions are limited to the original 8 cups in Time Trials. This code removes that limit by searching for the instructions in LE-CODE that handle the amount of cups at a given time, and overwrites the li r28, 8 instruction with: lwz r28, 0x2894 (r30), which loads how many cups there are in the distribution.

NOTE This could CORRUPT your SAVE FILE currently, so please be careful and not save ghosts outside the first 8 cups.

A lot of good codes were made by many people this entire year. We see some new faces as well. So with the end of 2019 here, and 2020 is just around the corner, I'd figure I would make this thread. Post your Top 10 fave codes that were made in 2019. Doesn't matter what they are, just list your personal favorites.

Here's mine...

1. Remote Code Execution [Star]
Summary: For obvious reasons

2. Screenshot [Star]
Summary: What an awesome code, take a pic of your screen anywhere and it saves to your Wii. Use Star's computer program to convert it to a viewable image.

3. Automated License Unlock + VR/BR Mod [Vega]
Summary: Something I always wanted to make as all the other unlock codes are pretty poor. Unlock everything for every license for all your data saves. Just run it once and you're back the Wii menu!

4. Draw Text to Screen [Star / Rii]
Summary: So useful, as using YS's Draw code is super long, and this one works on Dolphin. 

5. Perfect Start Everytime [JoshuaMK]
Summary: I can't recall how many times a burnout has made me upset lol. Ty so much for this code Joshua!

6. Wheelie Never Times Out [JoshuaMK]
Summary: Hate doing Chains? This code is for you

7. Live Replay [Vega]
Summary: First ever controller-free Live replay. I made this for obvious reasons. Only 4 lines in compiled length.

8. Exception Recovery [Star]
Summary: Doesn't stop every freeze code, but ty Star for making this! It helped against quite a bit of noob freezers on ALTWFC

9. Auto POW Dodge [Seeky]
Summary: He just made this yesterday! Something I always wanted, tried to make but couldn't. Seeky to the rescue.

10. Perfect Character/Vehicle Selection [Vega]
Summary: Always get the best char/veh combo based for w/e track+CC combo is the next race
