i think a new app is called for. "adfboot."
It would not work. Most demos and games poke the hardware in their trackloader routines.
Anyway, there already is "adfboot", sort of: Just mount RAD and copy the adf on it. Boot.
As you'll find out, most games won't load from RAD (the bootblock loads, but soon after the game will attempt to load rest of the tracks from the DF0, resulting in error or crash).
