I don't think any of them successfully run Super Monkey Ball 2.

Just installed Dolphin Emulator to my Shield TV last night.. If you are using the Shield controller(s), you want to first install v4.0-8766 here --> http://dl.dolphin-emu.org/builds/dolphin-master-4.0-8766.apk , then configure your controllers from THAT version...THEN, AFTER configuring your controller, install the latest/newest "Developmental" version directly over top of the Dolphin v4.0-8766 as an update to the already installed v4.0-8766 (The controller configuration that you set already will carry over to the new build.). Last night when I did it, I ended up finally installing v5.0-361, which is at http://dl.dolphin-emu.org/builds/dolphin-master-5.0-361.apk , although a newer build will probably be posted up already when you install it.

I have version 5 running on my gaming PC, added it to Steam, and access it through Gamestream on the Sheidtv

I personally use 4.0-8830
