m30 support is... disappointing. If any of the devs are Mega Drive/Genesis fans, they should/must give it some more love. It is a quite popular controller too...

Also quite a good controller for arcade.. in theory.

Anyway, I hoped to give some end-user support here:

Then again, they don't even configure the Game Boy Advance emulator to work correctly with a PS4 controller out-of-the-box. Guess xbox same thing.
