Not 100% up to date on DS emulators. As long as it runs accurately, shouldn't be an issue. Be sure to put Emulator and version number in the details of your submission.
German shouldn't be an issue. This game (as far as I can personally ascertain) was only ever released in Europe.
This game and whole series are partially under construction as we continue working to straighten out the series and the information we able to find about them (currently, the information available online regarding these games is very sparse). It may be that sub categories will be created later to resolve issues pertaining to languages, so your run may be moved appropriately when and if that is determined necessary.
You should be good to submit your run for the time being.
