How do I reverse engineer/decompile/recompile gamecube games?

[Chronosfabula]

Where do I start and where do I look? I found a few resources mentioning ghidra and I am able to decompile the project. I am still trying to learn how to recompile and interpret the code. Would a Gamecube SDK help with understanding the functions? Is there a group or discord I can reach out to to show me methods or steps on how GameCube games are specifically decompiled? I googled around and am still unsure if there is a direction I should follow

Respectfully, if you are asking such a question, you likely are not going to be knowledgeable enough to make considerable progress (I say this as someone who works in the technology field and am confident in the fact I am not educated enough in this space to conduct such a feat).

However, if you are serious about moving forward here, I would be ecstatic to someday see a GCN recompiler (I presume it would mostly work with Wii as well, given the architecture is similar, I believe).

I wish you the best in this space. If you're serious about it, here are some resources that will likely guide you in the right direction (take this with a grain of salt as again, I by no means consider myself an expert)

I suspect Dolphin's source code will be of use here, which can be found at https://github.com/dolphin-emu/dolphin

The N64 Recomp project, while a different architecture, will likely have a lot of folks educated in this space and is likely a good project worth referencing in terms of achieving a similar end goal: https://github.com/N64Recomp/N64Recomp

A quick Google search found this Github organization: https://github.com/doldecomp
This is likely to be useful as well and may be worth getting into contact with. I understand that the N64Recomp also made use of existing by-hand decomps in order to help understand accelerate the static analysis tool

I'm only loosely familiar with Ghidra, but likely it's a fine tool to actually reverse the binaries. I assume it provides instruction sets, of which you probably will want to cross-reference in the Dolphin repo to understand what it is doing.

Do not under any circumstances touch the Nintendo SDK.

Once you do, your project is now in legal risk (i.e. Yuzu).
