The safe and legal way to obtain is to pull it directly from Nintendo's own servers using specialized desktop tools. Method 1: Using NUSGet (Recommended)
The (Input/Output System) is the heart of the Wii's software. It's a collection of drivers and other low-level software that allows the main System Menu and games to interact with the console's hardware, such as the disc drive, USB ports, and graphics card. Various games and applications require specific IOS versions to function correctly.
For this file to be useful in a homebrew context, the base IOS38 it contains must possess a specific vulnerability. This vulnerability is known as the Ios38-64-v4123.wad
For someone exploring homebrew, the ultimate goal is often to run USB loaders, play games from a hard drive, or use emulators that require deeper hardware access. This is where a key distinction comes in: while the intention is to get a custom IOS working, the steps often involve the file as a building block.

The use of IOS38 as a base wasn't arbitrary. In the early days of Wii homebrew, developers needed a stable, well-understood IOS that contained the Trucha Bug. IOS38 met this criterion. Moreover, early custom IOS creators, like Waninkoko, built their installers around IOS38, making it the go-to base for many foundational homebrew tools. This historical significance has cemented its place in the modding canon, even as newer, more flexible bases like IOS56 and IOS57 have become more common for primary cIOS slots.
If you’ve ever ventured into the world of Wii homebrew, specifically to run USB Loaders like USB Loader GX or CFG USB Loader, you’ve likely stumbled upon a file named IOS38-64-v4123.wad . It might look like random numbers and letters, but in the Wii’s architecture, this file is a cornerstone of modern softmodding.
