I had issues with the controller pak as it showed up as "Unknown peripheral" until I cleaned the edge connector thoroughly.
I can't actually see any real difference in video quality between the HDMI adapter and composite video directly into the TV actually.
I may remove the composite output bodge so as to make it look nicer, but I may not.
So, the console has:
Expansion Pak
Controller Pak
2x controllers
HDMI adapter
