So glad I got this, works almost flawlessly. Worth every cent.I bought this dolphin bar a couple of months ago and it works pretty good.Theres no problems with it and its pretty easy to use.Perfect! Works great with the PC. We emulated Wii games using this. Awesome. Arrived earlier than expected.I just bought one of these and I found that it is exactly what is needed when you use Dolphin emulator to play your Wii or Gamecube games on the PC. It makes using the Wii remote easy which is a big change from before when you spent hours getting the Wii remote to detect with Bluetooth. And once the Wii remote is detected it stays detected, even when you turn off your PC and then start it up again, Dolphin will see your Wii remote immediately, no need to go through reconnecting it.The Wireless Sensor DolphinBar had some earlier compatibility problems when Dolphin released dolphin 3.5 but they are fixed now so if you are still having any troubles then just go to their site and get the latest drivers and make sure you are using the latest Dolphin Emulator version. In fact, As of 4.0-2241 and that DolphinBar firmware update, all of the DolphinBar's compatibility issues have been resolved!You can get the latest updated drivers from Mayflashs sitehttp://www.mayflash.com/products/nintendowiigc/w010.htmlAnd you can get the latest Dolphin Emulator version for Windows, MAC and Linux here:https://dolphin-emu.org/download/I found that this sensor bar is much more sensitive to my Wiimote than the Nintendo sensor bar and that is a plus for sure.Also this Sensor bar acts as a Bluetooth detector!!! So you don't need a bluetooth adapter to use it. In fact, I think it works better than the Azio I was using. It detects and properly recognizes the Wiimote within seconds and you will see it correctly identified and working in Windows which, I am sure you already know, is a problem if you are not using this Dolphinbar.This Dolphinbar has a small blue LED light that glows steadily when the Wiimote is connected and it will blink if the Wiimote gets disconnected for any reason.Here is some information from the Mayflash site:W010 Upgrade Firmware Ver04 Updates on February 10, 20151. The SYNC LED (LED 0) will be off if NO Connecting with the Wiimotes. The SYNC LED (LED 0) will stay lit if connecting with the Wiimotes.2. The DolphinBar will not enter into the sleep mode while in the Mode 4 (Dolphin Mode) with Windows 8.1 (Some customers feedback this problem before)Description:Wireless Sensor DolphinBar can connect your Wii Remote Plus Controller to your PC by Bluetooth.

Click this button to update.4.Please don’t unplug the DolphinBar when it’s upgrading.BETTER THAN EXPECTED WORTH EVERY PENNYThe DolphinBar has four modes which you can read about in the product's manual - mode 2 and 4 being of most interest to me personally and many other people.For me, as a light gun enthusiast, mode 2 can be used to make your Wii remote (and nunchuck) act as a mouse and keyboard - outputted as separate RAW mouse and keyboard devices by the DolphinBar.What this means is, with two of them, I can connect two Wii remotes to their respective DolphinBar, and then use something like DemulShooter (https://github.com/argonlefou/DemulShooter) and point to those RAW input devices, as well as specify virtual buttons for something like the middle mouse button.Since you're normally only press what's corresponding to the left and right mouse click through A, B, C, and Z, while the nunchuck analog acts as the arrow keys, you can set up one of those corresponding arrow keys as a virtual key for the middle mouse button.Now for mode 4 it's pretty simple. It was created with the Dolphin emulator in mind and allows you to connect 4 Wii remotes to a single DolphinBar, which is a lot of bang for the buck.The LEDs that are used for the Wii remote's positioning while connected to the DolphinBar are adequate, however the cable itself that it uses for power is very short, so for longer distances you'll need something separate that's either battery driven or with a long USB cable for this purpose.What's missing is a simple app of some kind to rebind the controls while connected through modes 1-3 - this would really make the possibilities amazing without having to resort to something like the Powertoys' Keyboard manager to rebind the arrow keys on the keyboard for example.This workaround allows me to bind things like Coin and Start in arcade games by remapping the arrow keys to be something like 1,2 and 5 on the keyboard instead when triggered.Purchased to use on a Raspberry Pi running Retropie. It works really well once set up with a standard Wii controller. It remembers the previous setting so you don't need to set it up every time. Have only used with a single Wii controller but claims that alternate modes will recognise and track up to 4 Wii controllers simultaneously. Apart from syncing to the Wii controller, didn't need any other setup. MAME emulator needs configured to use this as a controller but that's easy, it just sees it as a mouse. It's a decent option, pretty responsive, less wires and a lot cheaper than my Aimtrak light gun.I was hesitant to spend this much money when a bluetooth dongle can be had for a fiver and a cheap sensor bar for a few quid.After wasing an afternoon on precisely the above combination I decided to bite the bullet and pickup a Mayflash Dolphin bar.Put simply it is a superb product which works straight out the box with minimal fuss. The documentation is bare bones but covers the basics: bottom line is plug it in to your PC, set the bar to Mode 4 using the Mode button on top, fire up Dolphin emulator, choose Real Wiimote in Dolphin's controller settings and check Continuous Scanning. Finally sync your Wiimote with the Dolphin bar by tapping sync on the remote and then on the bar.Remote buzzes after a few seconds and is assigned a number. Games work perfectly.In addition to the above the other remote modes let you use your Wiimote as a mouse (Mode 1). You can even switch modes from the remote rather than touching the bar. Simply press Home + Direction button to switch between Mode 1 and 4 (Native Wii mode). End result is I can fire up Dolphin and a game without even touching my PC keyboard and mouse!unwrapped it, read the manual plugged it in, tested out wii remote, connects instantly with the sync buttons, nothing unusual, tested dolphin found a lot of cursor shake, updated firmware cursor still happening, decided to randomly tape some cardboard over the sensor for my LEDS on my wall which receives the signal from the remote so i can turn on off (use them for streaming cheap simple lights) to prevent it from having some annoying issue with another remote, constantly googling stuff, tried dolphin again, 0 shake or jitter works perfectly even works with motion plus and skyward sword on dolphin. Its amazing..One bad thing about it, doesn't seem to do audio for the wii remote like its awful quality sound really awful ive had better with a usb BT dongle plugged in but i have headphones on i dont need that. The bar has mode 4 for dolphin a couple other modes and mode 3. Also it works with the pair wiimotes app just use it in mode 4 for it so it doesnt cause weird problems on the pc (due to the bindings of buttons as this is all built in and can't be configured on dolphin bar). Honestly its amazing. Good price Great fun in games. I have done multiple videos of using a wii remote in the pc using an actual nintendo WII to power the sensor bar. This one does that just in the usb i can finally unplug my wii. The sensor bars infrared light things and the bluetooth is built in. Honestly its so simple to set up. Its just.. plug in.. sorted. Remember to sit further back when using the IR on the wii remote like pointing forward at the screen so it can pick up the lights. It wont work if it is too close. If you want to see my videos just search me on youtube JaayOnPCBought for the Dolphin emulator, and it works flawlessly.If you intend on buying this, please do read the instructions. This is honestly very important, the bar has numbered buttons which are different configurations for the user. Some options are for Dolphin (aka Wii Remote pairing) but others are for desktop mouse navigation via a Wii Remote. With some options select, it might initially work with Dolphin.But yeah, I dug out my old Nintendo Wii remotes and paired them with the bar, with the correct option selected on the bar I was able to play my favourite games for the platform in 4K with real accuracy.. Incredible experience, would recommend.Ripped my Wii games collection, hooked up the DolphinBar and now I'm playing all the fantastic Wii games in super-sharp 1440p instead of the usual Wii-Blur-O-Vision - which always rankled at the time - and hooked up to my home theatre instead of TV speakers. Finally the Wii games look and sound as good as they play!The control is seamless, just like on a real Wii and the functionality of its controllers is exactly the same - works with Nunchuk, Classic Controller, MotionPlus, and through the Wii Remote pointing feature essentially allows the use of a lightgun on an LCD monitor, which is otherwise a no-go.I'm so happy with this purchase, the DolphinBar does exactly what you want it to and works perfectly.
