Homebrew Trying to get back in the loop but having issues.

[ikithme]

So its been since April 2015 since I've had the desire to pull out my N3DS and do stuff with it again, and I'm trying to get back in to the loop but I'm running in to issues, probably stuff I forgot.

My end goal right now is to get Xenoblade Chronicles in to a CIA, however a lot has changed and I'm having trouble figuring stuff out. I've tried getting decrypt9 working with the launcher hack using the old cubic ninja exploit to launch laucher.dat files, but I always get a black screen, then I see stuff about brahma and homebrew launchers and I'm just plain stuck, I have no clue where to start. I've kept reading on how to compile brahma but have had no luck with it.

Is there any guide on how to get what I need done? I could dl a cia file as my end all, but I'd rather learn how to do it myself since I have the cart sitting in front of me and I like learning new things.

Actually that's the issue I'm having, I pop launcher.dat on to my SD card and I get a black screen every time after hitting QR Code on cubic ninja.

Running N3DS 9.0 sysnand and 10.4 gateway emunand.

Have you updated your ninjhax to 2.5? May be the issue if you haven't. (Not sure how the current builds go with ninjhax 1.1 to be honest)
And which QR are you referring to?

You do have the cubic ninja cartridge I assume? If so you have the homebrew starter pack on there as well?

Just use HBL (BrowserHax or what ever Exploit works for you) and load the 3dsx file

In CubicNinja you hit Create then hit QR code, and it exploits in to the Launcher.dat, unless I'm wrong x.x it's been so long since I've done any of this. How do I update ninjhax to 2.5...

I have the cubicninja cart but I use it to load the gateway menu.

How do I go about doing this from my current state outlined in the above posts, this I guess is where I'm getting stuck, running a NEW3DS I'm not exactly sure where to start on getting this part working.

Yeah that would be for the GATEWAY Launcher.dat, they're totally different.

1. Spaces are bad. Unless surrounded by quotes i guess
2. What python version are you using? And which D9 version? I'm guessing one of the versions from the link i posted earlier.

Spaces are in quotes using python 2.7 and yeah the d9 that you linked above.

Edit: Same issue without spaces :\

Ah i see the problem... using the wrong script
You're using ncchinfo_tgen.py when you should be using ncchinfo_gen.py

No love for the UI D9 version?

Weird... these python scripts need to be done away with imo. haha (i can't think of a way to replace them though)...
Investigating...

--------------------- MERGED ---------------------------

Just as a test, try just drag n drop the game onto the script and see what happens, rather than running from cmd.

Dragging and dropping does not yield any results, cmd comes up but then goes away almost instantly, no ncchinfo file.

I've had this problem before a long while ago and i can't for the life of me remember what the hell the problem was... argh!
I just tested the script myself (with the same game but EUR version) no issue. hmm

--------------------- MERGED ---------------------------

Are you sure the backup is good? (process of elimination time)...

--------------------- MERGED ---------------------------

Something else worth trying (i guess) is this.... the script converted to exe with py2exe so everything it needs is self contained. (it's not malicious, i swear.)

Backup is good, able to load the 3ds file from gateway and it launches with no errors.

I tried your zip file however I cannot extract it, gives me an error. :\ Not sure why.
