DIOS MIOS (Lite) is a modified MIOS made by Crediar that allows you to play GameCube games via an external USB device or SD card. Note that not all games work. Some may have streaming audio issues and some require a disc (any disc) to be inserted. See the compatibility list here.

Once it's installed WiiFlow can use it to launch GameCube games. You can also use DIOS MIOS Booter by Fix94 to launch GC games.

Note: This method of is no longer recommended. Use Nintendont Wii instead.

User guide

What DIOS MIOS doesn't do

• Allow use of the Nintendo GameCube Microphone.
• Play backups from writable DVD media.
• Play audio via disc audio streaming.

How to setup

Before using DIOS MIOS (DM), ensure that your Wii has GameCube support. Wiis sold after late 2011 do not have the necessary controller and memory card ports to run this software.

• DIOS MIOS (DM for USB) - Make sure your HDD's first partition is FAT32 with 32KB cluster size and primary and active.
• DIOS MIOS Lite (DML for SD) - Format your SD card to FAT/FAT32 with 64KB/32KB cluster size for best results.

Place the WAD file you downloaded in the wad folder on your SD card and install it with WAD manager.

It's important to note that you can only have one version of DM or DML installed to the internal NAND FS at a time. However, you can use the latest revision of SNEEK DI to launch either version automatically.

See this guide for how to rip your GC game disc.

Folders created by DiscEX, GCReEx, or DMToolbox should be copied into a folder titled "games" in the root of the USB or SD. Make sure to keep your backup loading software up to date and properly configured for use with the latest DM(L) release.

If you need to use an accessory in slot B, enable "Cheats" in your loader to prevent DM from patching fwrite where it's expecting a USB Gecko in that slot.

Uninstall

DIOS-MIOS (Lite) can be uninstalled by overwriting it with the default MIOS.

On PC:

• Download NUS Downloader. Navigate the Database to the latest MIOS (System > MIOS > v10).
• Make sure pack WAD is checked on the bottom and then click Start NUS Download.
• Navigate to the folder where you extracted NUS Downloader and open the titles folder.
• Now open the folder 0000000100000101 > 10 and copy the RVL-mios-v10.wad to the "wad" folder on your SD card.
• If you don't have one yet, download a WAD Manager and put it on your SD card.

On Wii:

• Launch your WAD Manager. Use it to install the WAD you downloaded above.
• If it asks for an IOS to use, you can choose 249, 250, 236 or generally any non-stub IOS.
