Homebrew [Release] Hello World

[JoostinOnline]

This is just a template for anyone who wants to get started on text-based 3DS homebrew, and doesn't care about it looking good. It is the bare minimum for running an app, but notes are included. It is of no use to people who don't want develop apps.

How to use
You need some basic knowledge of C of course, but I've included some notes in the code. Here are some commands:

• make: build a 3dsx (NINJHAX) and cia (Gateway) executable.
• make clean: delete the previously built files.
• make run: Runs the homebrew file in 3dmoo so you can at least know if it works.

How to make it look nicer
Using printf is easy, but it's not pretty. Using colors can change that. I made a file to easily do just that.

1. Save this as color.h in the source folder.
2. Add #include "color.h" to the top of your source file.
3. Use SET_COLOR(x) whenever you want to switch the font/background color, where x is any one of the colors listed in color.h

PS: I'm aware that another Hello World app exists, but it is far more complex and uses a custom font.

I made file for changing the font and background color.

What error?

ewin00 Lol, like I said in the post, it's of no use as an app alone. It's just a bare-minimum template.

Good job.

I just found out that WinterMute recently added a hello world to ctrulib (almost identical to mine, since they are the same principle), but I'm leaving this up because of the color.h file I made.

Kelton2 Your ctrulib is out of date.

 

[JoostinOnline]

Either use GIT to get the latest version, or just download it here. Next, extract it (if you downloaded the zip) and open command prompt in \ctrulib-master\libctru\. Type "make install" and press Enter.

 

[JoostinOnline]

make install also gives me error 2....

You need to tell me what the errors are. Try "make", then "make install".

 

[JoostinOnline]

It's because you have a space in one of the folder names. Change "ctrulib-master (1)" to "ctrulib-master", or anything else without spaces. Run "make clean" before "make install", just to be safe.

Btw, to copy everything in command prompt, right-click on the text, choose Select All, right-click again, then paste it anywhere.

I really should seriously study C code instead of overlooking documentation.
If only I wasn't so dumb I could handle better than basic stuff. I wish I could contribute.

You should add stuff to the makefile for building a CIA; I looked at the makefile and don't see anything like that.

That's a good idea. Thanks.

Does anyone have a Gateway cart?

Edited for bitchy people:
Who here has a Gateway cart and is willing to test?

Does anyone have a Gateway cart?

Uhh yeah, lots of people do, I included. Do you need help with something?

Lol it's late. I meant "Who here has a Gateway cart?".

Could you test if this works? http://s000.tinyupload.com/index.php?file_id=35849755458230979506

Nope, sorry. In the Gateway menu it just appears as a blank white square, with no title text when you highlight it. If you select it nothing happens; it just shows up as if no cartridge is inserted.
