DIT Arduboy + SD boot?

Hi, Like some people here, my Arduboy is a DIY one, the pin connections are a little different, I also have an SD card connected with CS on pin 4. Has anyone here ever experimented with something like the following SD boot-flasher

To load games without a PC? It would be nice to at lease pave the way for some of the features that people want to see in an Arduboy2.

You could look at the Gamebuino’s bootloader.
