ROM Hack how do you remake a cia file?

[gaberilde]

i extracted a cxi file and mangend to edit it and stuff and now i want to remake it as a cia. How do i do that?

First you rebuild the cxi from the header, exheader, romfs, exefs, plain, logo... (not all of these elements required, depending on what you started with): a typical tool for this is 3dstool

example: 3dstool -cvtf cxi whatever.cxi --header header.bin --exh exheader.bin --exefs exefs.bin .........

Then you create a cia from one or more ncchs (= cxi & cfa) using makerom

example: makerom -f cia -o whatever.cia -content whatever.cxi:0:0x00

hi i tried the first command and it said header not found but i dont have a header only exheader its not the same as romfs is it?

You can rebuild a . 3ds file, then convert it.

hi im not trying to rebuild a 3ds file just yet im trying to extract a cxi and i did that then i edited it and then maybe rebuild it as cxi or cia or whatever

No, header and exheader are very different (and of course an example is just an example, you need to adapt it to your files and your filenames - read the help built into those programs!!)

If you extracted it in GM9, the header is likely called "ncch.bin" or something similiar

Or of course you may not have extracted it at all - you will need to do so to rebuild it, of course

yes i got it i used a different extracting program and i found ncch.bin and it worked! thank you very much

hi how do you rebuild a 3ds file now?
i changed the commands and now it says the ncsd header is too short i used ncsd i guessed it would be it?

hi how do you rebuild a 3ds file now?

I could tell you (change the media type in the exheader, rebuild ncch, makerom -f cci -o whatever.3ds -content whatever.cxi:0) but makerom has a cia-to-cci mode
