Hacking Question What is required to write hello world on Switch console?

[Randall Stevens]

The main requirements are:

1. Handwriting skills
2. A permanent marker

Assholes on this thread really, REALLY need to resist posting.

I'm looking directly at you.

You will need:
* devkitA64 (includes the properly-configured versions of gcc and stuff that build code for the Switch's processor, available on Windows, macOS and Linux)
* libnx (builds using devkitA64, and so can be used on all three platforms)
* A publicly released userspace exploit

What? But I tried and it worked!

PS: Everyday that passes I get more disappointed of people, it is not their lack of skill at language what disappoints me, it is that on the one hand they have complete lack of sense of humor, and on the other hand they don't know what is an asshole and get hurt by a simple joke. Fucking snowflakes, the world will eat your guts.

less insults and sarcasm please, and more real answers like machinoman or CreeperMario.
thank you.

the question is legit, please provide a proper answer or don't post if you don't know.
Why is it so complicate?

This combined with the previous explanations on how to set up NodeJS and run the loadNRO script is all you need. Hello world is as easy printing out a string after that. In terms of homebrew not much can be done yet unless your really like ASCII art/text adventures, as much more work needs to be done before HID/GPU/Sound is useable.

What does op mean? Cant you change your profile name to Hello World

Opening/Original Post, or Poster.
it's referencing to either the first message of this thread, or the user who wrote it.
there is a "OP" logo displayed on the avatar of that user to easilly identify who started the thread or asked a questions. it's useful when multiple people are helping him, we can see who helps and who asked it without reloading the first page to check the username.

I know what op means I meant what does he mean when he wants to write Hello world

Is this a serious question about writing "hello world" in homebrew? The first stage is getting a pointer to the screen buffer memory address so that any value written there will output directly a dot you see on screen. The second stage is to set aside a graphics buffer with pixel pictures of A-Z 0-9 and all the ASCII characters. So instead of writing the characters manually yourself, you can just call a function with the text. If the SDK can support a screenprintf("hello world"), then that means you got graphics and text output to the switch already.

It would be nice if a pointer to the sound buffer and a way to get controller input are also provided in the SDK.

I don't know if they can expose the graphics API provided by the firmware, but the first "Hello World" should offer direct access to the frame buffer?

I think someone mentioned that you can set linux style carriage return on Windows Subsystem for Linux (WSL). How do you do that? And someone mentioned the NRO not running under WSL, how do you get it to work? Why isn't anyone trying to do the whole thing from beginning to end on the Windows 10's provided Linux mode? Why complicate the whole process with VirtualBox? I think someone mentioned you also need to virtualize the network devices if you use VirtualBox (so many steps, not everyone has a full guide). I think a guide for Windows 10 WSL should be done.
