Please kill this post if it is straying too far. If you download the DLC using NUSgrabber for Wii Sports Club (USA# 0005000c10144d00), then generate a 3DS TIK, you can use Cdecrypt or New-NUSgrabber to decrypt the contents into a Loadiine format. Using masqchips Loadiine mod, you can enable no legimate DLC and Tennis will work in MiiMaker mode. I haven't had time to play with it, but creating separate AOC files like for Hyrule Warriors does not work. It actually stops Tennis from working. Just thought I'd put this out there for others to play with. For a Loadiine Mod that plays all the sports see: https://gbatemp.net/threads/loadiine-mod-y1-dlc-on-sd.447048/ Do not ask how to find the encoded title key on that Title Key site. I think it is OK to link the TIK generator site.
