Can I boot directly to flashcart menu?

Hi!

With my NDS with Hiyacfw and Unlauncher, I can set what the system boots into when turning the DS on.

Can I do that with by O3DS with Luma3D? I have a shitty R4isdhc (the one with Bomberman as a launcher „app“) and I’d like to boot into that instead of waiting for the default, SLOW 3DS system, then launching the R4 menu via the game icon and THEN launching the NDS game.

Thanks!
