Could someone compile a small 3DS homebrew app for me? (.3dsx + .cia)

[AllisterMKW]

Hi everyone,

I’m learning Nintendo 3DS homebrew but don’t currently have access to a computer.

I wrote a very small test application that fills the top screen with solid colors
(A = red, B = blue, X = lime green).

Would someone be willing to compile it into a .3dsx and a .cia for me?

The full source code and Makefile are provided below.

Thanks very much!

Mate, I had to create a new makefile and add some resource files but here is the build:

Now you can build de .3dsx file by running:

make all


And the .CIA file by running:

make cia


I am attaching the source which I used and the binaries. I used MSYS2 to build it and installed the packages:

3ds-portlibs
3ds-dev
3ds-sdl-libs

A guide to install MSYS2 on Windows can be found on https://gbatemp.net/threads/setup-a-devkitpro-environment-on-windows.652238/#post-10712513 this is for Switch but you can install the packages and will build 3DS sources too.

I own this account. In fact, I accidentally double posted because I just created that account and it was awaiting approval. I have a new source code package and was wondering if you could compile this one instead.

I fixed the makefile and updated the source code for the CIA to include information such as the author, icon,, and banner. Could you please compile it one more time? It would make me very happy and I won’t bother you again!
