The next milestone of this project is to get the Cart with the flash drive and Bluetooth dongle connected back up to the Raspberry Pi and successfully run a simple game rom.  

Ammo Can Chassis Tasks: 

• The spacers to hold the cartridge connector to the Ammo can chassis was completed and the chassis just needs to be drilled out and the connector installed. 
• Pins used for the USB bus need to be soldered to the breakout USB A connector that will go from the connector to the Raspberry Pi.

Cartridge Tasks:

• Find and add USB splitter to add Bluetooth dongle to flash drive bus. 
• Select and solder USB breakout to NES cart pins

System Tasks:

• Prep the Raspberry Pi 2 B+ with Retropie, verify that power and video still work.
• See if the Joycons can be added as controllers with the Bluetooth dongle. It looked like there was someone with a working solution here

Anticipated Challenges

The big question is even though the USB will be electrically connected, they might not be able to support the file rates needed for the flash drive and bluetooth over some haywire in a box. The backup plan is to just have something that copies over files to a larger medium plugged right into the device bypassing the hack-n-slash.
