Dumping games with Godmode9

Dumping games is the act of taking a game from your system or gamecart and copying it into a readable format onto your SD card. Dumping is perfectly legal if you keep the dumps to yourself, however sharing these dumps is piracy and is illegal.

This guide will tell you how to dump games from various formats and for various purposes. Dumping 3DS cartriges as .cia files is good if you want to install them to your system. Dumping them as .3ds files is good for emulators. Installed titles cannot be dumped as .3ds files. NDS cartiges can only be dumped as .nds files and cannot be installed (however, you can play them with emulators or flashcarts).

Dumping the RomFS of a game is primarily for romhacking purposess. RomFS is the place where a game stores its data. If dumped and modified, these files can be used with Luma's LayeredFS feature to patch games.

Many instructions here are adapted from Plailect's Godmode9 Usage page. Check it out for more information on Godmode9's functions.

This guide requires Luma3DS, b9s and Godmode9. If you do not have any of those, please follow the guide.

This page contains a lot of information. Only follow the section(s) relevant to you!

What do I do after I dumped files from an cxi file.
I simply want to install the game, so I guess I have to create a cia file now.
Can anyone tell me how?

Edit: Nevermind. I found, that you can simply build a cia from the cxi.

@MakashiDev I have the same problem as this guy, and I just updated Godmode9.

@MakashiDev @Pikrioling Taking a wild guess here, maybe it's been renamed to "Search for files" in recent versions?

@ehx-v1 actually, you press Open Title Manager, then select the title you want to do stuff with by pressing A, select Open Title Folder, selcet the .tmd file and then press TMD File Options.... There press Mount CXI/NDS to drive, enter path go to the file/folder you want to copy, press A (or R + A if you're copying a folder) and select Copy to 0:/gm9/out. The Romfs should be there after it's done.

@Pikrioling Ah, so that means "Open Title Manager" is the new "Search titles".

I am not sure what causes this, but your godmode9 might be too old/outdated. Try updating it and following the instructions again carefully.

I am encountering the same issue as the person above, and I double checked and my Godmode is up to date. Perhaps there's been a mistake by whoever writes the guide.

@AlcalineAlice It seems that Godmode9 did some restructuring and the guide is slightly out of date now. Check the discussion right above your comment.

IMG_5766 Is there a way that I can extract the ROMs from the CIA files of my legal virtual console GB/GBC games?
