I got a big question. How can you do motion sensing on Dolphin when there's no sensor bar?
ok, it's a bit more conplicated, but you need an IR source.
It doesn't even have to be the Wii one, but it will give best result.
I could get a wireless one on ebay or anything (if you have the skill, you can even make one), but I chose to use a real one because....I payed for it, why not?
So,
1) Boot your WiiU in wii mode and just pass the prompt for he display with a wiimote.
2) pass the warning thingy.
3) you can at this point tun the tv off, but just make sure the console is always on.
4) unpair the Wiimote (easy method, remove the battery and put them back).
5) with your dongle plugged, you can now use the wiimote standalone. To pair wih your computer, have a program that can test it and press the sync button. You normally would use the 1 and 2 button, but this will cause the wiimote to pair to your WiiU while the sync requires you to push the sync button on the WiiU, but the way the dongle will work is that it's like it's permnently pushing it for your pc has it's constantly searching. This will force he Wiimote to pair to your pc while the WiiU is still on wii mode.
6) you're actualy done!
Yeah, dolphin when lauch can have an option for continuous search so, lauch the game then press sync.
Why do you want your WiiU on in Wii mode, but not paired to it?
It'a because the Wii sensor bar needs to have power. In WiiU mode, it will only give power if there's a wiimote detected which we do not want to pair (unless you have a second wiimote, but that's another thing and even then, disconnect after not touching it).
But it's constantly on in Wii Mode so, you want to get in there.
However, you HAVE to have a wiimote paired to pass the display prompt so, you have no choice but to first pair the Wiimote on the WiiU and pass the prompt.
Once in wii mode, you have a working sensor bar but we need to pair it up to the pc. That's when come my sync button technique.
As for the sensor bar, the wire is ridiculously long so just mae sure it is either on top or bottom of your screen and set the location in dolphin depending on what you choose.
Add hdmi cable and it's litterally like the original environment, but with dolphin.
My pc is decent enought to ALONE maintain 60fps, but beware, good cpu needed and a good gpu will help, but cpu is way more important.
Then, add the fact that I have a second monitor which I got for 20$ (seriosuly, I culd not refuse this the resolution is 1280 x 1024 and it supports vga which even then, is better than my laptop screen).
But I could hook hdmi to my tv....it just is more complicated.
I know you might feel jealous, but the dongle only cost 15$ how could I possibly refuse that?
