Setting up FNA for UWP

	YOUR APP:
	- Make sure in App Properties, “Min version” must be Fall Creators Edition (16.....)
	- In Package.appxmanifest, change the Entry point to <NAMESPACE>.<MAINCLASS>, not the XAML stuff.
	- In fact you should get rid of all XAML Files.

	FNALIBS:
	For all dependencies:
	- Compile in 64-bit Release mode.
	- Retarget to latest build versions if necessary, but try to keep Min Windows SDK to Fall Creators Edition.
	- If any project asks you to retarget, right click the SOLUTION (not the project) and click Retarget Solution.

Sending data to the Mega Drive over USB using the Mega EverDrive PRO

Mega EverDrive PRO Overview

The Mega EverDrive PRO has a USB port (much like the EverDrive X7) which allows you to send arbitary data to the Mega Drive over USB. With the X7 you could simply send data to the USB serial device and pick it up at a specific memory mapped location on the Mega Drive. With the PRO, however, you need to wrap the data in a "command" and send it over the USB serial device, so that it will be available to the Mega Drive.

The following information was obtained by reading the source contained in the MEGA-PRO repo.

Command Message Format
