Note: this post assumes you use a very recent version of makerom (makerom 0.14 should suffice:
https://github.com/profi200/Project_CTR/releases).
Do not copy and paste the commands you see here, read what this post says, and substitute in your own named files.
To make your own banner (only a 2D one will be covered here), make or get a PNG file that's 256x128 in dimensions, and make or get a WAV file that's 3 seconds in length, or less, if you want a banner with sound. Then you'll want to get bannertool (
https://github.com/Steveice10/bannertool, or grab the binary from
https://github.com/Steveice10/citrus/tree/master/tools), and run it as follows:
Code:
bannertool.exe makebanner -i nameofyourpngfile.png -a nameofyourwavfile.wav -o banner.bnr
If you don't want sound, I believe you can omit the -a argument (need to verify this though).
To make your own icon, it's pretty much the same process: get a PNG file that's 48x48 in dimensions, then just run bannertool again:
Code:
bannertool.exe makesmdh -s "Your Game Name Here" -l "Your Game Name Here" -p "Author Name Here" -i nameofyouricon.png -o icon.icn
Then to combine it all into a CIA, you need to use makerom. You'll need an RSF file, which tells the 3DS what sort of services the program can access, what to name the game, and things like that. Here's an example one that will probably work for most homebrew programs (if the program you're trying to make a cia for already has an rsf, you might want to use that instead; it might require services that this example doesn't provide, though you could just edit this example too).

Anyway, now you're ready to build the cia. Use makerom:
Code:
makerom -f cia -o install-me.cia -DAPP_ENCRYPTED=false -rsf rsffilename.rsf -target t -exefslogo -elf yourelffilename.elf -icon icon.icn -banner banner.bnr
If you want to spit out a .3ds file instead, it's more or less the same:
Code:
makerom -f cci -o runme.3ds -DAPP_ENCRYPTED=true -rsf rsffilename.rsf -target t -exefslogo -elf yourelffilename.elf -icon icon.icn -banner banner.bnr
That's about it.
