Homebrew Modded DSi Autoboot?

[Hephaestus]

I have a modded DSi XL equipped with Twilight Menu.
I set it up quite a while ago and i cant quite remember if this is possible.
I basically want it to do this:
If no keys are pressed during boot it should boot twilight menu, just like it already does.
If a certain button is pressed, maybe X, it boots straight into my flashcart.

Can this be done?

Yes. If you're on an old Unlaunch version, please update.
Then after updating, press POWER, then hold A+B, and go to Options.
