I can try to answer any questions, but it doesn't seem like the 8bitdo Ultimate software is availible for download yet. Im not big into mechanical keyboards, this is actually my first, so I don't have much direct comparison experience to other keyboards.
but the buttons are big and f u n.
Mine has been posted. Looking forward to it! Been using a Durgod with my MiSTer but the lack of dedicated F keys made me want the 8bitdo.
