Community:Gates to Infinity DLC Editing Tutorial

DLC Editing Tutorial for Template:GameTitle. This can be useful for making a .cia file that doesn't include unused downloadable content (or that only includes such content), or for creating custom DLCs such as custom music or dungeons.

Note that the terminal commands used on this page were used on Linux. On other operating systems, such as Windows, minor adjustments may be required.

Requirements

• Basic knowledge of command line tools
• A .cia file of the original DLC (named gti_dlc.cia in this tutorial)
• CTRTool (https://github.com/3DSGuy/Project_CTR/releases/tag/ctrtool-v1.2.0)
• MakeROM (https://github.com/3DSGuy/Project_CTR/releases/tag/makerom-v0.18.4)

Extracting the DLC

Run the following command to extract the Contents from the .cia to the current folder.

./ctrtool --contents=contents gti_dlc.cia

Rebuilding the DLC

Before continuing, you need to create a text file with the name "gtidlc_rom.rsf" and that contains the following text:

Option: MediaFootPadding: true EnableCrypt: false SystemControlInfo: SaveDataSize: $(SaveSize)K

Choose which Contents files you want to include in your DLC .cia file. Note that "contents.0000.345057da" must be included. Names of the Contents files consist of four numbers/letters (the first part), followed by a dot, followed by a longer sequence of numbers and letters (the second part). When mentioning them in the MakeROM command, you need to add at the end of the filename ":0x", followed by the first part, followed by ":0x", followed by the second part. For example, "contents/contents.0000.345057da" becomes "contents/contents.0000.345057da:0x0000:0x345057da".

These are examples of what the command might look like.

This command makes a DLC .cia file that only contains DLC that was officially distributed.

This command makes a DLC .cia file that only contains the unused DLC music tracks (Craggy Coast, Star Cave, and both versions of Vast Ice Mountain Peak).

./makerom -f cia -rsf gtidlc_rom.rsf -o gti_eu_unused_music_only.cia -ckeyid 0 -major 0 -minor 1 -micro 0 -DSaveSize=0 -ignoresign -dlc -i contents/contents.0000.345057da:0x0000:0x345057da -i contents/contents.003f.296877ae:0x003f:0x296877ae -i contents/contents.004c.42b26fec:0x004c:0x42b26fec -i contents/contents.0062.04434456:0x0062:0x04434456
