However, I do believe they’re entering a very oversaturated market, with the likes of 8BITDO and GuliKit creating high-quality, affordable controllers in the same niche. ANBERNIC would have to aggressively outprice them to get any kind of attention, but only time will tell.
Not really. 8BitDo really blew it with the Ultimate. They confusingly have two different “versions” of it, and neither have the full range of device compatibility that previous 8BitDo controllers had. The most egregious exclusion from the Ultimate was Xinput over Bluetooth. I still have no idea why they decided to drop that.
Its design takes inspiration from a modern-day Xbox controller and is fully compatible with PC, Steam, Nintendo Switch, Android, and iOS using Bluetooth 5.3 and 2.4g connection. It can also be connected using a USB-C wire too.
If this new controller has Xinput over Bluetooth, all of the compatibility from above, and a strong battery life, it might be a day 1 buy. It will have hall effect sticks, so this sounds like everything I wanted the 8BD Ultimate to be. I hope there aren’t any showstoppers once reviews start coming out.
If you don’t want to open this and solder a chip, then no, you can’t do what you want.
The closest you can get is to enable AutoRCM, which will cause the Switch to always boot into recovery mode and accept a payload. This skips the need to use a jig in the Joy-Con rail, but you still need to inject a payload. And because recovery mode is just a black screen, you don’t have any visual feedback to know if the Switch is actually in recovery mode, or if the battery is just dead.
Your best option is to just boot into whatever OS you use most, then make it a habit to keep it charged enough to not shut down.
