@Sophie-bear maybe try dumping them again. Some games i have the header file broke from converting them to cxi and then back to cia. Thats just me but i think that may cause it to fail too.
Just a wild guess

Yeah, I'll try a few things and see if I can't come to some conclusion of what the cause might be. Thanks

I'm running into it again with some other .cia files.
Could them being created with the wrong version number maybe cause this somehow? A couple I have are like that and coincidentally when I start installing a batch with them is when I start running into the problem again.

I’m not sure right now. I’ll create a version of custom-install-finalize that prints more information to help figure out what this issue is. The wrong version shouldn’t matter much though, since this program only installs a ticket and seed, and doesn’t do anything with the actual title.

Though this error is strange and I'll have to look into it, DSiWare titles can't be installed to the SD card, so you have to do it the old-fashioned way.

Looks good to me so far. In this little example, I would probably rename logLines to log_lines to match PEP 8 and be consistent with everything else in the project.

Some of the methods should be split into their own functions, like one that starts writing a single title, one to update the title database, one to update cifinish.bin and add to it (currently it overwrites). Then start() should exist to call all of them to keep it simple for anything else that may use this.

Maybe it would be possible to create importable DSiWare that can be imported through System Settings? Although I am not sure if that would be any faster than just installing the DSiWare CIA on the console... But I suppose it could be useful to some.

so will there be a single .exe file instead of many files where we don't need to type or run any the command's ?

It's technically possible, but I don't know the format of DSiWare exports. Plus given their small size it wouldn't be that useful.

As soon as there is a gui fully implemented I will try to build and provide standalone exe and app forms.

@NekoBit I wonder. In the gui would a help menu with a web link to a guide on how to dump said files be useful to add?

Maybe in the README for now but a manual would be neat idea

NekoBit · Nov 7, 2019

Wish if I didn't have tasks in my way I could've finished it tonight, but it will wait until tomorrow.
I am sooooo close, but I think it will be pushed tomorrow.
Need to do threads, but the percentage works and all that jazz. Give it some time. The code is kinda messy too, it got kind of all over the place when I had to get the thing jumbled together, will make some room tomorrow to clean as well.

Fantastic, but I'll wait for the GUI because I lazy.

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

Also, what would 'Skip Contents' do?

--skip-contents means everything but writing the contents of the title happens (creating cifinish.bin and adding to title.db). This is useful if, for example a game was written to the SD, but it failed to add to title.db. You can use this to finish the install without rewriting all of the game's data.

custom-install is a Python 3.6+ tool that will install CIA files to a Nintendo 3DS SD card entirely on a PC. This completely bypasses the slow wireless and I/O speeds of the hardware.

This has no GUI at the moment, so you are expected to know how to use a command-line interface. It also currently does not verify CIAs, so corrupted CIAs may not show errors during install.

Example speeds installing Pokémon Ultra Moon, about 3.45 GB (does not include final step to install a ticket and seed):

Class 4 SD: 15 minutes, 15 seconds

Class 10 UHS-1 microSD: 2 minutes, 58 seconds

For comparison, FBI network install to a New 3DS with a Class 10 UHS-1 microSD: 48 minutes, 14 seconds

Thanks to wwylele and his work on save3ds which has made modifying title.db on PC possible.

Please read the README for usage details.

Should I create a GUI for you?

Quick tutorial:
FIRST AND FOREMOST, install Python and add it to the Windows path variable
Extract custom-install-master somewhere you want.
Paste boot9.bin seeddb.bin and movable.sed to the root of the custom-install-master folder
Take out sd-card from 3ds, download custom-install-finalize and paste it in the 3ds folder of your sd-card
Paste the .cia files you want to install to the root of the custom-install-master folder
Open command prompt, preferably with admin rights, in the folder custom-install-master
Insert the following code

Code:

py -3 custom-install.py -b boot9.bin -m movable.sed --sd *YourSDCARDDISKLETTER:\* *yourgamename*.cia *yourgamename*.cia

Wait for install
Insert sd-card to 3ds and open custom-install-finalize through homebrew channel
???
PROFIT!

Hi, can you tell me where I went wrong? Thank you in advance.

Make sure you're running that in the directory that custom-install.py is located in. If all the necessary files are not in the AM directory you're currently in, it won't find them. You can use the command "cd" followed by the path to the folder the files you're working with are in to change directories.

If I understand correctly, you're saying I should open CMD in the folder where "custom-install.py" "boot9.bin" "moveable.sed" and "seeddb.bin" are located? Please take a look (my folder's content):

That's right. Either Open CMD there or change directories to there after opening CMD. Doesn't matter which you do, same result.

Love! Could you teach me how please? I can't seem to figure it out admittedly

Wuigi · Nov 9, 2019

Worked really well for me, thanks for your efforts to make this program possible.
I only wonder where the CIAs are installed to, directly to the correct ID0/ID1/... paths?
@HalMuntz97 Shift+right click in the directory with the custom-install.py and select open powershell/open command prompt here.

Open a command prompt, then click in the address bar I've highlighted in my attachment (in the blank space, not on the text). Copy that text. type "cd" then a space in the command prompt, then paste that text you copied. Press Enter, then run the command you're using to install the cia files again.

You rock and a half, look at what you've helped me achieve. Thank YOU! :-)

This still requires double space in the SD memory, but the installation is much faster than the FBI

I have a error
