what would I all need to purchase to use a real wii remote with motion plus??

A wii mote with mplus in side or the adapter add-on but the internal mplus works great.
A bar for tracking the wii mote and mplus calibration.
A BT dongle.

For the bar, you can use one of the following:

A bought USB Wii Bar

A bought Wii bar plugged into a Wii

A bought Wii bar converted by yourself to work off batteries

A bought Wii bar converted by yourself to work off USB power

A bought Wii bar converted by yourself to work off a wall-plug transformer

A homemade Wii bar powered from a power source of your choice

A bought wireless Wii bar

If it's a Wii Remote Plus - https://wiki.dolphin-emu.org/index.php?t...tion_Guide

There's a link to a working toshiba stack dongle on the recommended accessories page - https://wiki.dolphin-emu.org/index.php?t...ccessories

If it's a regular wiimote, you can use the standard bluetooth stack in MS, so any bluetooth adapter will be sufficient. - https://wiki.dolphin-emu.org/index.php?t...ontrollers

Also, you'll probably want a sensor bar if you don't have a convenient setup that lets you put your Wii's sensor bar at your computer. There's a link for one in the recommended accessories link above.

how hard is it to convert it to work off USB?

Very.

Really easy if you have a soldering iron that works (it's quite a bit harder if yours is like mine and stays too cold), solder, and ohm's law. You basically have to reduce the resistors in there because USB gives a higher voltage supply than the Wii, and you want the same voltage across the LEDs.

In this thread https://forums.dolphin-emu.org/Thread-an...sensor-bar I explained my build process, and also derived an equation for deciding on resistor values. For it to be relevant, you'll need a voltmeter, a Wii you can plug the sensor bar into, and a screwdriver you can open the sensor bar with. It is as follows:

Rnew is the value of the resistance of the resistors you'll have to buy in Ohms.
Rold is the value of the resistance of the existing resistors which you found out from the coloured bands printed onto them in Ohms.
VLED is the value of the voltage across the LEDs in the Wii bar when you plug it into a Wii, which you measured with a voltmeter/multimeter in Volts.
Vold is the value of the voltage across the resistors in the Wii bar when you plug it into a Wii, which you measured with a voltmeter/multimeter in Volts.
5 is the number of volts USB outputs in Volts. If you feel less than confident about my memory, feel free to use a multimeter to test the voltage output of the USB port you're going to plug this into.

The equation:

Rnew = ( Rold * ( 5 - VLED )) / Vold

This is designed to work with sensor bars where one resistor serves both banks, provided you measure the voltage across the two banks of LEDs together, or where both banks are in parallel and each bank has a resistor, provided you measure the voltage across each resistor separately and each bank of LEDs separately.

Someone said USB ready bars are only $5, which is probably less than a USB cable and a non-USB bar, though, especially if you count the effort.

Can be easy. http://i.imgur.com/05ew9EL.jpg
Thats a battery powered one I converted to USB all I did was open it up and connect the power and ground wires off a USB cable to the + and - battery terminals and it worked.

I had the nouse to make a nice, neat hole in the back of mine for the USB cable so it'd screw together again and still be pretty. You've taken the other route and bundled it in tape.

Yeah couldn't be bothered to do it neat. Also there is a bundle of 4 pennys taped on the other side to counter the weight of the cable :p
