Hacking CIA to .3DS? (Decrypt9)

[Skeet1983]

I read somewhere that Decrypt9 can convert a CIA to .3DS format? Is that true? If yes, how do I proceed? Thoughts and help appreciated

Not sure it has a dedicated automatic feature (which would only benefit gateway users), but the procedure is:

1- fully decrypt the cia

2- extract decrypted cia to NCCHs using "ctrtool filename.cia --contents=ncch"

3- create 3ds using "makerom -f cci -o filename.3ds -content ncch.0000.seedumpedfilename:0 -content ncch.0001.seedumpedfilename:1 -content ncch.0002.seedumpedfilename:2"

steps 2 and 3 to be done on a computer with said software, obviously omit partition 1 (manual) and 2 (download play) if the game doesn't have them (step 2 didn't dump an appropriately numbered ncch), edit underlined parts with correct filenames


btw if you're asking for emulators, I think citra can run CXIs (so stop after step 2, rename the ncch.0000.* to filename.cxi)

I have a side question: For dumping a gamecart, what do I need to select in Decrypt9 to make it work with Gateway?

I suppose it's just Dump Cart (full) or dump cart (trim). That way, it will also work on sky3ds+
