Yeah, I tried that, but all I get is "Unknown file" in return. I performed these steps:
1. Download ctrKeyGen and padgen (old versions, I think, since these are still .exe -- As I said, github confuses me.)
2. Donwload getromfs and xor.exe (from
Twili here:

3. Drag the Tomodachi Life ROM onto ctrKeyGen to get ncchinfo.bin
4. Put the resulting ncchinfo.bin and the Launcher.dat (GW version) onto the root my SD card
5. Run the exploit and let the 3DS generate the xorpads
6. Drag the Tomodachi Life ROM onto getromfs.exe to get EncryptedRomFS.bin
7. Use HxD to trim the CTR-P-EC6P0.romfs.xorpad to match the size of EncryptedRomFS.bin (I just had to shave off a bit of the end, right?)
8. Drag CTR-P-EC6P0.romfs.xorpad to xor.exe to get DecryptedRomFS.bin
9. Run ctrtool.exe -x DecryptedRomFS.bin --romfsdir=TomoLifeDecrypt
10. Get error =(
All files on my computer were in the same folder
