I can finally achieve the dream of arduboy gaming on the big screen without any controller cables. Made a youtube vid on it here: https://www.youtube.com/watch?v=je5CKsIrNw8
Thanks uXe for donating the vga1306 board and all the work you have done for making video output possible as well as Blinky for your work on the flashcart! All I really added was the custom board to make wiring everything up a bit easier for prototyping and adding a bluetooth receiver (with an atmega328p to handle receiving controller commands and pulling buttons) so I could pair with my wireless modded snes controller. I have one more simple change I will probably make, the controller was built for nintendo classic consoles so I added a home button on top that I will probably reuse to trigger the reset button so I never have to get up from the couch to press the reset button to go back to the arduboy flash loader screen.
