Learn PowerPC for Wii Cheat Codes Index

This is a gigantic index of threads that will take any absolute beginner and teach them much of the PowerPC Assembly Language for the purpose of creating Wii Cheat Codes. This is NOT a "general" PowerPC tutorial. There are certain concepts that are taught in a different manner that is suited specifically for Wii Codes. However, you can use this to learn PowerPC regardless.

All threads must be read in listed order. This will NOT be something you learn in just a day or two. It will take some time. Be patient and read thoroughly. For most of the threads provided, there are also video links as well. However, some of the video links have become extremely outdated and you should only watch the video(s) if absolutely necessary.

Requirements before you start:
  • Have a modern computer
  • An ISO/WBFS file(s) of whatever games you want to make codes with, on your computer

Even though this is a Mario Kart Wii based site, you can use these tutorials to help you make cheat codes for other Wii games.

You will need what is called the 'Dolphin Emulator' installed on your computer before you begin. You will also need to know a few things about running/playing Dolphin plus installing a program called 'Dolphin-memory-engine'. Here are 3 threads you need to read and complte first...
After you have completed those 3 threads and you can run MKWii (or your desired Wii game) at 60 fps with the Dolphin-memory-engine working, then proceed.

If you have unresolved issues with Dolphin Emulator, it's best to ask on the Dolphin Emu forums - https://forums.dolphin-emu.org If you have unresolved issues with Dolphin-memory-engine, post an issue at this link - https://github.com/aldelaro5/Dolphin-memory-engine/issues

Now let's begin!  Smile

RE: Go From Noob to Veteran ASM Coder - Vega - 12-22-2019

I realized I should probably make a video series on Wiimm's Tools

RE: Go From Noob to Veteran ASM Coder - JoshuaMK - 12-22-2019

I can definitely help with the Wiimm's Tools tuts. For goodness sakes I even know how to create an LE-CODE distribution with it. The only issue is that I generally don't get a chance to record stuff....

Maybe keep it on hold for me for a few weeks and if I still can't put some videos out by then, then you could do it? Trying to lighten your load some lol Tongue

RE: Go From Noob to Veteran ASM Coder - Vega - 12-23-2019

Just started the series. Intro vid uploaded. Was working on the next video, but have to refilm it.

https://mkwii.com/showthread.php?tid=1744

I highly doubt I'll do videos for these, who knows


Also, I'll probably end up merging the new Float thread with the thread about Converting Floats to Integers. Kinda silly to have those two things in separate threads. Read post below

RE: Go From Noob to Veteran ASM Coder - Vega - 06-13-2021

The thread that had just the mini guide of converting floats to integers is now added into the Working w/ Floats thread. Forgot to mention awhile ago I added in the Logical Operations tut to the list.

EDIT: Added the Paired Singles tutorial
