Homebrew boot directly on game

[samlach22]

Hello, is it possible to boot the 3ds directly to a game, like MCU bricker ?
Thanks

I've not seen any examples of that being done with games before... However, if you're just interested in messing with the notification LED like the MCU bricker then it should be possible to take some of Sono's source code here and build it into your own custom Luma boot.firm. If you wanted to switch the notification LED "on boot" and after sleep then you could stick it in the sleep.c file of Luma.

Can you tell me the procedure to modify the file boot.firm, or create a custom Luma boot.firm
Thanks

Maybe Google it. It's often a good solution

I used this guide here to build Luma. You'll probably come across a few issues but they should be solved by replies in that guide. Hope that helps.

Hello, sorry to answer so long after the last discussion, you're talking about a file named "Sleep.c" it's impossible for me to find it in the unzipped boot.firm.

In addition, in the tutorial, it says that you just have to type "make" in the CMD, but this makes a mistake that indicates that "make" is not a valid command.
Thank you for your answer

Ah sorry, you are right, there is no sleep.c file in the basic Luma. I'm too used to tinkering with Nanquitas' version (https://github.com/Nanquitas/Luma3DS/blob/master/sysmodules/rosalina/source/sleep.c).

It's been a while since I set up my environment... Assuming that you configured you're environment variables correctly then it might be that you have taken the old version of makerom. I posted about that on the last page of the tutorial. Try the one from this thread.

I'd suggest repeating step 11 to make sure your environment variables are set. Then try 'make' again from x:\Nintendo3DS\Source\ctrulib\libctru where you see the 'Makefile' in that directory. 'make' doesn't appear in the makerom help menu but it will work if the environment variables are set.
