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.
Make sure the battery is topped off but yes mine does light up, at leas in the 2'4ghz mode
Oh that sucks, mine doesn’t. I have no interest in peeling off the feet to get at the screws to open this bad boy and see if the polarity of the LED is flipped or if there’s a bad solder joint. Usually I like to watch a tear down video first so I’m not trailblazing/making disassembly missteps.
Maybe reach out to the manufacturer. They may help you…
Awh man thats terrible. Sorry about that :( hopefully the rest of the board works fine otherwise Id be sending a strongly worded email.
