Feature request - Use controller buttons to start other boot.dol

[keiem]

Should it be possible to add the feature from picoboot, to use a controller button to start a certain game while booting?
Example:
I don't have a lot of GC-games and most of all, I play Mario Kart Double Dash. So I want to have Mario Kart Double Dash as my boot.dol. Let's say I occasionally play Super Mario Sunshine. So I could boot into Super Mario Sunshine while pressing A-button during boot. On another day, I have friends comming over and they want to chose a game? Then I could press X during boot to boot into swiss-gc.
