I don't want to be the noob, but... one question comes to mind.
Would it be possible to create a CFW using python for 4.5, or is it too limited?

 

it would be nice if someone just post how to do a simple hello world on both screens and HOW TO SET UP THE ENVIRONMENT and building the necessary files
i know a little how to program (java oop) but i don't know well how to set up the environment (on linux maybe)
hope someone reads this a does a little tutorial

Also can you use a python ide for coding ?

 

To set up the enviroment, install:

https://launchpad.net/gcc-arm-embedded
http://www.python.org/

Then add python to your $PATH. Build.bat will then compile whatever your C\ARM code is into the Launcher.dat.

As far as how to set up the makefile and all that, I can't help you, I don't know that much yet. But I was able to get other users code running and am studying what they did.


Now, to get the launcher.dat to actually do something once it's on your SDCard, get a copy of Fierce Waffle's ROPLoader.nds from the first post, put it on your DS-Mode flashcart, run it, press home instead "A" once it's verified, then go into DS Profile and it should launch (Or crash, but if it crashes then ROPLoader worked)

 

It's a very limited kind of C, as we don't have true 3DS headers but yes the Python script is just for compiling Launcher.DAT.

I recommend downloading some of the other homebrew and reading through their lib folders for an idea of what commands are available.

 

Yes.

 

If you use Kane's build script(https://github.com/insaneKane/3DS_Homebrew_Stuff2/blob/master/build.py), make sure to change both instances of
"-mcpu=mpcore -march=armv6k"
to
"-mcpu=arm946e-s -march=armv5te".

 

Yes, basically reverse engineering libs right now. No one has barely and knowledge of the ins and outs.
