Peltz is correct, it’s a “Download Play” game that is beamed from Wii to DS and persists as long as you keep the DS powered up.
However it’s possible to use some Wii homebrew to extract the game from your Wii, and some PC homebrew to extract the NDS ROM from the Wii game. I did this, and then setup a flash card to autoboot the game. Just to have a dedicated DSlite for just MaBoShi. 
Guide (no rom)
It’s the last opportunity to buy this wonderful game MaBoShi on Wii right now.
