I uninstalled 2.0 today. It's so buggy. Downloaded all movies, wheels etc. for MAME. Artwork displays no problem in HyperQ, can't get them to show in HS even after clearing all the caches multiple times.
Wheel sounds work sometimes, other times they don't.
Every time I boot up up HyperQ it redownloads the same 40 or so MAME preview videos even though I have them. It's been doing this ever since I installed it 2 months ago.
What did it for me though is the joystick support is bugged when navigating the exit menu. It just doesn't work, and I refuse to start using JoytoKey again on the new version.
Maybe I'll give it another try in a year or so.
