#618 

## Description of change
The game expects the main display to be *not* HDMI, and at port 2.

Hooking DisplayConfigGetDeviceInfo allows us to boot the game on any
monitor.

Add basic I/O hook. It gets stuck in `USB I/O Checking...` for a couple
minutes but it'll eventually skip and boot to title screen.

## Testing
ugh.
