A Complete List of IOS Files and their Functions (Updated)

This is a list of known IOS files and their functions in the architecture of the Wii system. Each IOS performs different operations based on the application that is running. Your Wii probably won't have all of these IOS' installed. Every console has a different number of these pre-installed based on their region and date of release.

Each IOS is indexed below by category based on their purpose. It's up to you to keep the IOS files your system needs up to date once your Wii is softmodded. Note that IOS included with the 4.3 update are not necessary or needed at this point to run any game.

In the case of System Menu IOS 11/12/30/50/60/70 and Korean 40/52, an exception is noted which displays the version of the stub installed when the official firmware update has exceeded that System Menu.

As you can see, some of these are still blank. If you know what function they perform, post and I'll add it to the list.

===========================================

Never uninstall any IOS below 200!!
Unless specifically instructed by a Wiihacks Recommended guide. :)

Some of this list was compiled from the information in DOP-IOS MOD, some from NUS Downloader,
and some from ShadowSonic2's SystemMenu/IOS List. Wiibrew's resources were also referenced. Credit for that information goes to the authors.
Mods if anything needs to be corrected/added feel free to do so or let me know.

When GH5 was first released, I read somewhere that IOS56 that was installed with GH5 may have been used for something to do with the downloadable content being saved to the SD card, is there any truth to this? I see that you list it as being used by Wii Speak. The source from where I read about IOS56 would not be concidered a reliable source, just something I remember reading.

I think some users were using the cIOSCorp DIP-patched version of IOS56 to get their dlc content installed, but it only worked for disc users or some such. Don't quote me on that though, I'm not entirely sure what all was involved with it.

Ios16-v257
Used by the official Nintendo Backup disk v1.3
Ios has trucha bug, es-identify, and flash access

Ios236- ios36 patched and installed to ios236
Ios237- ios37 patched an installed to ios237
Done with dop-ios-mod v10, and probably versions of TBR.

Is there a way to know which ios files are currently installed on my system? I am having issues with a couple games and the only thing left I can think of is maybe a missing ios file or two. I have tried installing some but wad manager will not allow me to do it using ios 249, only 250, and I don't even know if the install was successful.

Run Signcheck through HBC. Press reset many times until it's finished and view the CSV it creates on your SD card with your pc.

There's a similar function built into the latest DOP-IOS MOD, but I've been testing v11.5 pretty thoroughly and it's definitely buggy with cIOS38Rev17, so stick to using Signcheck until a more compatible DIM comes out. You can also use DOP-IOS MOD v10 to update the IOS files you need within the console.

And Wad Manager shouldn't have any problems installing with IOS249. Make sure you're using WM v1.5 and try reinstalling your cIOS as sometimes they get a bad install.

Thanks again. I will try to use dop ios mod. I believe I have ver 10 but downloaded the link in ShadowSonic2's post in case I don't. I will try reinstalling cios38rev17, but I am almost positive I had to install wads from 250 from my original mod for some reason. I hope I didn't miss something during that process.:confused:

250 is just a clone of 249 installed to a different slot. So if 250 works in Wad Manager but 249 doesn't, that tells you there's probably an issue with the 249 install. And using r17 of cIOS38 I'm guessing there might be complications using an earlier version of wad manager.

Worse case scenario if you can still install under ios250, that and DIM will get you by for the time being until you can figure out what's causing the issue with 249 in Wad Manager.

Thanks for that info. I will have to figure out what the problem is, or reinstall if possible. I am pretty sure I had to use 250 for wad installs even during my mod.

Informative, organized, and easy on the eyes as usual. Thanx for sharing your talents.
