Nintendo Wii Diagnostic Disc Source Code

Edit on Github | Updated: 29th March 2026

In the Nintendo leak on 20th July 2021 an archive called DIAG4RVL.7z was released to the internet, this archive contains a CVS repository containing 3 different software development kits for the Wii (codename Revolution).

The three folders that were contained inside this archive were:

• DIAG - Internal Wii Diagnostic Tool Source code
• RevoEX - Extensions to the Wii SDK
• SDK - Version 3.2 of the Wii SDK

The reason the SDK and RevoEX folder are included is they are dependencies required to build the DIAG tool from source.

The Wii SDK has been released before and we will have a separate post covering the contents of that folder in the near future. This post will focus on the contents of the DIAG folder.

Introduction

Before going into depth about each of the files contained in the DIAG4RVL tool source code there are a few important things to note about the software and the hardware it runs on.

What is DIAG4RVL?

Initially it was thought that the name DIAG4RVL just meant Diagnostic tool for Revolution (Wii), however it seems to actually be version 4 of the Diag tool, with version 3 being used for the Gamecube.

Who used DIAG4?

DIAG4 was only to be used internally at Nintendo, apparently due to security issues. It is used to diagnose hardware issues with consoles. Presumably if you send a faulty Wii to Nintendo this is the disc they would put in the console to see what needed fixed.

When was it released?

The first release of the DIAG4 tool was in December 2005 and the last release (1.6) being released on the 8th August 2006 just a few months before the retail launch of the Wii.

Although according to the documentation file DIAG_4_9_readme.txt there was a version 4.9 released on the 9th of January 2009.

What hardware did it run on?

It is to be run on the Wii development kit hardware (NDEV) but it is currently unverified if it runs on retail Wii hardware.

How are the logs written?

The log files that are written during the execution of the tests are sent to the connected PC using one of the two tools:

• Barnacle (USB, RS232C connector)
• Waikiki (USB)

What variants exist?

There are multiple variants of the Disc based on which parameters you supply to make, they each perform different tests.

The variants and the tests they perform are:

• Master - Runs most of the tests
  • Disk Name: RVL_DIAG_Ver4_91 (015E)
  • runs tests: full_auto aging_test sort_auto gfx_auto gtop_auto gekko_auto mem_auto manual info
• Aging - Runs tests to check how well the hardware ages
  • Disk Name: RVL_AGING_Ver1_0 (100J)
  • runs tests: ?
• Master DIF - Board Checking tests
  • Disk Name: Board_Checker_RVL_F (123J)
  • runs tests: Board_Aging Other
• Master uji - Possible for Retail Consoles?
  • Disk Name: RVL_FINALIZED_DIAG_Ver2_0 (124E)
  • runs tests: sorting_f manual_f aging_test_f
• NEC - Seems to be a disc specific for a NEC hardware test
  • runs tests: NEC_auto info

How is it built?

The Wii (Revolution) SDK is required to build the Diagnostic disk just like any wii game, so the DIAG4RVL.zip handily contains the wii SDK included in the folder SDK.

To build the SDK you need a working Wii SDK along with Cygwin, when you have that simply run the bash command to make the master disc image:

make master

What does the build scripts execute?

As far as I can see building the DIAG4 Disc involves a number of different tools:

• mddl - Windows executable that takes in a .MDL file and builds a DVD_ROOT folder
• makedol - Converts the nmenu.elf file into a Gamecube/Wii executable .DOL file
• ndstop -
• rvl0.pl - Perl script to?
• unix2dos -
• elf2rom -
• MakeTestPattern -

What are all these file formats?

Here is a brief description of the main file formats you will encounter in this codebase:

• DDF format - seems to be the definition of the data to be written to a DVD such as the game name, company. Or it is used to emulate folders on a PC to act like they are a DVD for the development kit.
• MDL format - Used by MDDL.exe seems to describe all the different diagnostic tests split into groups such as Board_Aging etc

Docs (/docs)

There is reference to both Hollywood and Hollywood-1 (Bollywood) in the document from 2009, Hollywood is the original version of the Wii graphics chip and Hollywood-1 is the second more secure version aslso known as Bollywood. The references to Hollywood-1 and Bollywood are in the document diag_attention_for_MP.txt but are all in Japanese so it is hard to understand exactly what it is saying.

One of the most interesting documents here is the diag_gfx_check.jp.doc file as it explains three different methods for verifying that the graphics hardware is working and code examples of how to use each one.

The main window is split into 3 top sections:

• DIAG - Lists all the tests along with their 2 byte unique ID
• GROUP - You can group multiple DIAGs together by dragging and dropping from DIAG to GROUP
• MASTER - You can drag and drop items from either the DIAG or GROUP lists here and only these tests will be written to DVD root.

Under the DIAG list there is a bunch of toggle buttons such as GEKKO these filter the DIAG list to only include the category of tests that have been toggled.

The files in this folder are described in the table below:

The project was written using Borland C++ Builder and if you have the IDE you can open the project file mddl.bpr.

The Unit1.dfm file can be edited in C++ Builder as it contains the layout of the main Form. The implementation that goes along with the form is Unit1.cpp and has the code for loading the MDL file and populating the form.

The code for Unit1 is fairly standard C++ Builder code so it might not be particularly interesting to you, unless you are interested in the MDL format.

What is more interesting the reverse engineers is the source code for the makedol tool which is contained in makedol.c. This tool converts compiled ELF files into the Gamecube/Wii executable Dolphin file. This can be worth a read if you have ever wondered about the difference between .DOL and .ELF files.

If you are interested in the DOL format, it is partly documented in this WiiBrew page: DOL - WiiBrew

Include (/include)

Interesting information in the diaginfo.h file is that it mentions Bollywood which is a version of the Hollywood graphics chip, with added security (preventing the Trucha Exploit).

It also mentions the following information:

Uji (/include/uji)

This folder simply contains one top level include which is used to include all the files in the sub directory /utility.

Utility (/include/uji/utility)

The most interesting part of this codebase is the LayerSystem allowing easy drawing of Menus with Images and Text, very useful when creating gamecube/wii demos.

If we didn’t already have multiple homebrew examples showing off similar functionality this would be a great library to recommend for anyone wanting to create some simple 2D interfaces on the Gamecube!
