Hacking Boot slot-1 card automatically instead of going through the 3DS home menu?

Sweater Fish Del · Sep 21, 2021

There's several DS games and homebrews that I use my 3DS for more than anything, whihc means I usually end up switching to my slot-1 flashcard after booting my system.

Is there any way I could streamline this process of getting to the slot-1 card without even having to load the 3DS home menu?

Something like open_agb_firm that could be run as a Luma payload, but to boot slot-1 in TWL mode would be ideal. I've searched around, but can't seem to find anything that does this. Maybe it's not possible?

Why don't you just dump the games and homebrew to your SD Card and use TWiLightMenu? It's much easier than using a flashcard.

Is there a way to boot TWiLightMenu without having to go through the 3DS menu?

If not, I don't see the advantage. In fact, TWiLightMenu actually takes a bit longer to load than just booting the flashcard in slot-1.

I believe there is a way to load a NDS cart on power up, but I've only done it with ntrboothax. Other than that, I don't think there's any homebrew to modify the startup software.

I don't think that's possible, the forwarders are the closest to that for now.

Oh yeah, the START+SELECT+X with the lid closed trick does boot from the slot-1 card. As far as I can tell it only looks for a 3DS firmware on the card, though. It won't boot it into TWL mode.

Tons of homebrew modifies the startup, though. Basically any FIRM that can be run from boot9strap or fastboot3ds. And actually boot9strap and fastboot3ds themselves. open_agb_firm is probably the closest to what I want to do, though it's a lot more complicated since it has a file menu and totally replaces the stock AGB_FIRM, but all I want to do is boot into the regular TWL_FIRM. I'm pretty sure what I want to do should be possible, but it certainly doesn't look like anyone's released anything to do it.

Maybe I'll have to look into it myself.
