What is this:
cxitool is a useful PC app that converts *.3dsx homebrew executables directly to cxi's, which are the building blocks of the CIAs that all you pirates know and love. This app was released a few months ago, but is was buried in a devkitpro repo so it has largely gone unnoticed. The author, fincs, has chosen not to publicize it for whatever reason, even though the source is public. I assume it will be a part of a devkipro update sometime in the future, but that seems like forever given there has not been an official update since January.

This can be very useful for instances where the 3dsx author has chosen not to provide a cia, and has the source code closed (or too difficult to compile). A lot of older 3dsx homebrew has suffered this fate and this app could be of great benefit to making them more accessible to a new audience.

Instructions:
Usage: cxitool [options] input.3dsx output.cxi
Options:
-n, --name=<value> Specifies the process name of the application
-c, --code=<value> Specifies the product code of the application
-t, --tid=<value> Specifies the title ID of the application
-s, --settings=<file> Specifies the settings file
-b, --banner=<file> Specifies the banner file to embed in the CXI
-v, --version Displays version information
-?, --help Displays this text


Example usage:

cxitool game.3dsx game.cxi
makerom -f cia -o game.cia -target t -i game.cxi:0:0

I have attached a windows build for your convenience. It has been verified:

So has anyone been using this yet? It works well for me, but the occasional title doesn't convert if I add too many arguments. The default config I showed in the Example Usage seems to always work though.

Umm, help? Trying to open this asks me for some DLL files, and putting them in the same location as the file and then opening it gives me this error:
The application was unable to start correctly (0xc000007b). Click OK to close the application.

hey can you help with my issue?
I have no idea what dlls it's looking for. Maybe try compiling it yourself. That's what I'd recommend anyway with instead of trusting exe's from some stranger :P

not that im out to hurt anybody but still

At first I thought this is used for converting official games to cia, but then I quickly figured out that this is only for the developers.
It clearly says in the title, 3dsx to cia, lol. It's even repeated in the first sentence.

Now, this begs the question: if converting 3dsx to cia is possible, shouldn't the reverse be possible? If it is, you have to wonder if CTR-SDK apps could be converted to 3dsx. There would be a lot of issues to work around, sure, but it's something to think about.

it's not that easy, especially because of romfs, memory mapping and stuff

Exact same issue here.
