Homebrew Converting .elf to .cia? How?

xXDungeon_CrawlerXx · Oct 10, 2015

Hey Guys,

I want to convert some .elf files to .cia files by myself and I know that I have to use makerom for it.
But I really don't know how to use it :/

Someone who can explain me how to build a .cia (with own Banner, Name and sound)?
would be awesome!

If nobody beats me to it, I'll write up a mini-tutorial later (probably leaving soon for the night, so I can't do it now). It's not really difficult, just a bit tedious.

You have to use a banner tool to create banner and icon and makerom to create the final cia.

This 3dbrew wiki article should help.

read the Nyan Cat 3DS port thread, there is an easy script

He knows that, but "use makerom" is easier said than done. There's a lot of stuff to consider (like rsf files) and a lot that can go wrong.

But you can still google it

And he can always ask back if it didn't work for some reason.

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).

Code:

BasicInfo:
  Title                   : "Your Game Name Here"
  ProductCode             : "CTR-P-EDIT" # You can make this whatever you want, it doesn't have to follow the Nintendo standard

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.

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.

THANK YOU!

It worked very well

Thank you again

Okay, got a little problem.
Tried to use a sound for my built cia (.wav file, size: 380kb, length: 3sec, bitrate: 1024kbit/s).
But I only hear a few beeps when using it.
here's the wav I use: http://www.xup.in/dl,13612937/audio.wav/

is it possible to get it to work?

Not an expert, but that seems like a really high bitrate for a 3ds. That wav file is enourmous.

Deleted User · Feb 22, 2016

Usually, the wav files have to consist of the following properties to actually work on a 3DS:

It needs to be stereo.
It needs to be no more than 3 seconds long.
The frequency has to be 32000Hz.
And the bitrate need to be 32-bit float.

(These are my findings from a couple of months back, anyway...)

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).

Code:

BasicInfo:
  Title                   : "Your Game Name Here"
  ProductCode             : "CTR-P-EDIT" # You can make this whatever you want, it doesn't have to follow the Nintendo standard
  Logo                    : Nintendo # Nintendo / Licensed / Distributed / iQue / iQueForSystem

#RomFs:
  # Specifies the root path of the read only file system to include in the ROM.
#  RootPath                : $(APP_ROMFS)

TitleInfo:
  Category                : Application
  UniqueId                : 0x1337 #Something like 0x1337, but you can make it whatever you want, as long as it's a hexadecimal number (probably best to make it something actually unique though!)

Option:
  UseOnSD                 : true # true if App is to be installed to SD
  FreeProductCode         : true # Removes limitations on ProductCode
  MediaFootPadding        : false # If true CCI files are created with padding

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.

I constantly get:

[EXHEADER ERROR] Invalid cpu speed: 0x256MHz
[EXHEADER ERROR] Failed to create ExHeader
[NCCH ERROR] NCCH Build Process Failed
[RESULT] Failed to build outfile

Any fix?

Should be 268Mhz now, if you're using the latest makerom, and no need for the "0x" part, it's not a hexadecimal number.

i made a video tutorial + a batch file to do it all

but how are you supposed to change it to something other than a hexadecimal number

Homebrew Converting .elf to .cia? How?
