Dokapon Kingdom Netplay change Language

[vullprofiman]

I managed to get Dokapon Kingdom running with Netplay with Dolphin Version 5.0-3975 but it is always in english.
(in the newest Version it is in English too but I get some kind of error when I start the game can't write bt.dinf to syscon, so I am using an older version)
In both PCs the language of the Wii is set to German.
If I start them without Netplay the game is in german.

Is there a way to change the language the emulator uses in Netplay?

You can edit the sysconf in the blank NAND for all users.

Where can I find this sysconf?

The blank NAND is hidden in the sys folder which should be in the same folder as the Dolphin executable. You'll find a Wii NAND root that's mostly empty.

I found the sysconf but it is mostly gibberish to me. I opened it with wordpad. Could you tell me what to edit to set the language to german or where I can search for the info on how to?
