…It also looks cool how it's just one .exe program no extracting anymore ;0

I'm pretty sure she got that idea from me.
Would you like me to host your programs, @Asia81 ?
If you haven't already, I can also add your copyright info like I did to the ones I tried making for you.

@Asia81 I tried out the new build and test entering the numbers, and it worked for me! Here's just to show that it worked

Uh... I did it long before you, I just stop to compil in 4.7 :/

Yeah, but not now, thanks!

Your tools now work properly for me, but the generated 3ds game won´t start. It tells me everytime I try to start the game, that the gamecard was removed.

Oh, so it wasn't my versions of 4.6 that were the firsts? Good to know.

Yeah, but not now, thanks!

Just let me know when you want me to upload whichever programs you've made to my hosting server, I'll update the link page afterward.

[Asia81]

Could someone try a new build?

Try to open 3DS Builder and other tool with writing 1, 2, 3 or 4 in the main menu.

Could ONLY someone with spaces in their windows usernames try it?

Please?
What I meant by space in username

Is there a tutorial somewhere to decrypt and rebuild DLC/Update files?

I want to change the music in the Smash Bros DLC.

Hi, trying to create .cia for X/Y rom hack, so trying to follow type 2. Running sysNand 9.2/emuNand 10.7, running HBL from sysNand, copied files to where they're supposed to be. When I run Decrypt9, I get:

Opening /D9Game...
Nothing found in /D9Game/!
NCCH/NCSC Decryptor: failed!

Am I missing something obvious? Have D9Game folder and empty PokemonY.3ds file in it

You need ncchinfo.bin along the game file

I'll have to check this weekend, my SD card reader died It might be the .3ds.3ds or something like that. That was my issue when setting up A9LH (boot.ini.txt)

Why do I need to use a Setup since 4.8? I'm not really trusting anything that has something to do with "hacking" and requires me to use admin rights on my Windows PC... Besides, VirusTotal shows a malware in that package, not sure if this is a false positive or a real thing now...

When i use HackingToolkit3DS.exe to extract the cxi it gives an error saying it can't find the directory to the specified file, can anybody help?

Have you posted sources for the binaries you include in your pack? If not would you be willing to do so?

As long as 3ds builder does not support newer 3ds games with update data and Partition7 partitions, your tool will only useful for past game and not newer. Lets hope 3ds builder will be updated.
