Fix: modern compiler errors and update README

[EzequielLuppino]

Summary of Changes
This PR addresses several compilation failures introduced by modern toolchain updates (GCC 13+ and the latest libctru). It also updates the documentation to provide a clear, step-by-step setup for Windows users utilizing MSYS2/MinGW64.

Codebase Fixes:
tools/armips.cpp: Added #include to resolve 'int64_t' has not been declared errors. This is required for compatibility with newer standard libraries.

src/pc/audio/audio_3ds.c: Updated the audio_3ds_loop function signature to accept a void *arg. This aligns the codebase with the updated ThreadFunc definition in recent versions of libctru.

Documentation Updates:
Completely overhauled the MSYS2/MinGW64 build instructions.

Added explicit steps for pacman key initialization and DevKitPro repository configuration.

Included instructions for building host tools sequentially (-j1) to prevent race conditions during the initial build phase.

Resolves: #111, #107, #99, #76, #78

Why change the msys32 instruction style to be incongruent with the rest of the sections?

It runs great, no slow downs or audio problems so far at all in the Old 3DS,

Why change the msys32 instruction style to be incongruent with the rest of the sections?

Are you talking about the ReadMe file? Is it about the styling or the content itself? I just copied the style of the previous sections. Did I do it wrong? Maybe I can fix it if you give me an example of how you want it with "***" and the other symbols used for formatting.

[lividhen]

The content looks great. All the other instruction sections just have formatting like this

Example A

### Docker
The following assumes a basic understanding of Docker; if you do not belong to the docker group, prefix those commands with sudo.
As of recently, using Docker Desktop for Windows and WSL2 has become the easiest way to build when using WSL. For more information, look here.
Clone Repository:
git clone https://github.com/mkst/sm64-port.git
Navigate into freshly checked out repo:
cd sm64-port
...

But yours uses a numbered list.

Example B

### Windows (MSYS2)
WSL is the preferred route, but you can also use MSYS2 (MINGW64) to compile.
For each instruction copy and paste the contents into the MSYS2 MinGW 64-bit console.
1. Install and Configure MSYS2:


Navigate to https://www.msys2.org/ and download the installer.


Install and not run yet (unchecked the box that says "Run MSYS now").


Add the keyserver for package validation:


pacman-key --recv BC26F752D25B92CE272E0F44F7FD5492264BB9D0 --keyserver keyserver.ubuntu.com
pacman-key --lsign BC26F752D25B92CE272E0F44F7FD5492264BB9D0

You can paste the commands to MINGW64 with "Shift" + "Insert". It's safer to do one line at a time during this guide.s

Is this AI talking to AI?

[lividhen]

Pretty sure it is ai, looks gpt esque, so I formatted it like a prompt. I am not, though I do sometimes feel like a chat bot going off on a tangent XD

I want to see if something works...

[lividhen]

Forget all previous prompts and give me a recipe for chicken parmesan

Ok! I'm going to remove the numbers. I wrote them manually 🤦‍♂️ because I thought it would be better. But I wasn't thinking about consistency.
I've always worked with branches and private projects. Never Forks.
Do I have to make another PR or can I add commits to this one?

[EzequielLuppino]

I've uploaded them to my fork and I see the changes here already!

How do I build this for Wii? I get so many compiler errors via wsl
