Homebrew Homebrew Development

[Wisenheimer]

I'm pretty sure we have full kernel access using this exploit, it just isn't really shown here. Theoretically we could create something like a Linux loader that boots the 3DS into Linux, change things around in RAM (and maybe ROM?) and other stuff. Basically, I'm pretty sure this exploit can be used to give us full access to the 3DS. But yes, it's limited to FW4.5.

If so, that is pretty awesome. If homebrew gets going in any meaningful fashion, I suspect people will work on figuring out how to overflow newer firmware.

I'd really like for people to start working on modifying the running 3DS firmware in a similar way to how Gateway does it, so that we can remove the region lock and do other features, such as taking full screenshots (top and bottom screen in a lossless format like PNG). But I'm not expecting that to happen any time soon. Plus I'm just saying that 'cuz those are the two big features I want, hehe.

Either way, any homebrew is better than no homebrew and I'm really happy to have finally run some form of homebrew on my 3DS.

Yeah, we have full system control, but we're basically just in a room with a bunch of blinking lights and flashing levers and no idea how to really take full advantage of anything. Though now that unsigned code is indeed running, hopefully more people will take notice

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)​

cant install gcc arm embedded on ubuntu 13.10 thought ppa .........any idea?
Also how do you quote a message from another user ?

Might have to compile it yourself. I use Arch so I just had to get arm-eabi-gcc from AUR.

To quote a user, hit "Reply".

so......where it is this AUR ?

I am not a big fan of imports, for the most part, but I just finished mother 3 (hand to use my phone and a community patch) so I know that there is quality games out there that are not being released in the US, like if you are a fan of the Fatal Frame series.

https://aur.archlinux.org/

Only useful if you're using Arch Linux though.

well thanks anyway
i will wait for the package to be aviable for ubuntu 13.10

Directly thought of this picture xD

This is for people frustrated by installation problems.
Direct links to correct Windows installers:
https://launchpad.net/gcc-arm-embedded/4.8/4.8-2013-q4-major/ download/gcc-arm-none-eabi-4_8-2013q4-20131204-win32.exe
http://www.python.org/ftp/python/2.7.6/python-2.7.6.msi

The reason to use installers is that you don't have to worry about editing PATH variables and all that nonsense.
Now just click on build.bat in the ready-to-go demo package to compile (attached below).

3 steps, can't make it any easier.

well thanks
but after i extracted it and added the $path when i try the python script it shows up this message

rm: cannot remove ‘obj/*.o’: No such file or directory

any idea

also i think the thing that any developer want the most (excepts for the libs), right now is a emulator
but dont know if it will be an easy task

First of all, did you set $path for the user that you are executing the script as? If you run the script as root, root's $path needs to be set. My guess as to what's happening is that it somehow can't find the compiler, then the rest of it gives errors because the compiled files do not exist. Not sure what's up with the Permission denied though.

Yeah, fails.

You can launch the python gui from windows start menu and run build.py - that seems to do something, I get a 3dsploit file open on the screen in wordpad.

Seriously - you guys need to speak english.

Explain how to build AND RUN a hello world program on either the top or bottom screen.

Which firmware versions of the 3DS console does this work on?

What files do we copy to the 3DS SD card - where? what directory do we copy to?

Maybe post a video if you can't write instructions.

 

[Snailface]

I've attached a makefile edition (built off of namidairo's makefile) of the toolchain -- no Python needed.
https://launchpad.net/gcc-arm-embedded/4.8/4.8-2013-q4-major/ download/gcc-arm-none-eabi-4_8-2013q4-20131204-win32.exe install this first.

Just double-click build.bat on your <= 4.5.0-10 3DS and place the Launcher.dat file on your SD card.
(should work in linux too ... hopefully)

 

[nop90]

I uploaded on github a small update with:
- Buttons management
- Fixed pointers for all six buffers

No buffer swapping at the moment, but now the program draws to both framebuffer to avoid blank screens if the second buffer is active.

I attached the executable for people who are not able to compile the sources. You should not execute it (I would not!) because it's very easy for a bad guy to brick your 3DS, how GW did.

Obviusly I'm not a bad guy :-) , but every bad guy would say this :-/

Anyway, try it at your own risk. I don't take any resposability.

yes i did add the $path (like it was written in the read.me file here) but still nothing

update:
i did some chmod and now this is what i get
