Dragon Quest X: Mezameshi Itsutsu no Shuzoku Online (ドラゴンクエストX 眠れる勇者と導きの盟友 オンライン) is a massively multiplayer online role playing game taking place in a world known as Astordia. Create a character and select multiple classes and five races: Dwarves, Ogres, Elves, fish-like Wedi and petite Pukuripo; each with their own continent and stories. Quest alone or in a party of up to four. Enemies roam the overworld and battles begin upon contact. Combat is menu based, with waiting times between each move, and players can move around the battle area as they please.

This title comes on two discs. Both are required to install the game data to a USB mass storage device.

Emulation Information

Large Install Size

On top of having two Wii discs, Dragon Quest X: Mezameshi Itsutsu no Shuzoku Online has a huge install file that can increase in size with online updates and expansions. Up to 16GB of space within Dolphin's user folder may be used. Please be aware of this when attempting to play this game.

Booting Dragon Quest X

When installation is complete, the Japanese Wii System Menu must be used in order to boot the channel. By moving the current Wii NAND root to a new folder, Dolphin can create a Japanese region Wii NAND complete with the Japanese System Menu. Booting the Wii System Menu option when that NAND is selected will launch the Japanese System Menu, and with Dragon Quest X installed, it will be bootable.

Japanese Shop Account Required

When using online mode, the game will check for updates by connecting to the Wii Shop infrastructure. Because the shop servers will only give information about the Dragon Quest X update titles if and only if the console region is set to Japan and matches with the shop account region, a Wii Shop account with the region set to Japan is required.

Failure to check for updates and update to the latest version will result in the Dragon Quest X server rejecting connection attempts immediately.

End of Service

The official servers for the Wii version of the game were shut down on November 15, 2017. Since then, the game has been unplayable except for the short single-player story.


Map Crash

When viewing the map, the game will crash if "Skip EFB Access from CPU" is unchecked. Until the cause is figured out, it's recommended to enable this hack to work-around the crash.

Keyboard Support

Keyboard support requires usbv5 support. Support has been added as of 5.0-5904

Incomplete IOS Emulation

Dolphin's IOS HLE is currently incomplete and does not have a full implementation of the WFS modules which are used by the game. It is unplayable as a result.

As of Dolphin 5.0-1837 WFSI and WFSSRV have been implemented to the point where the discs can successfully install the channel. Unfortunately the channel still doesn't run due to other missing WFS functionality.

5.0-5167 adds the necessary function to get in-game. Additional information regarding installation can be found at PR #5930 until WFS support is more complete.

Fixed in 5.0-5291


Only configuration options for the best compatibility where they deviate from defaults are listed.
