ROM Hack [Question] Can I extract a patched rom with RomFS Extractor?

[ZedMania]

This is probably a really nooby question but, as the title says, can I do this?

Basically I did all the stuff to patch Neo Y, and it works perfectly on my 3ds, but now after playing it for a while I've started to wonder if I can change the music. So instead of having to dump Pokemon Y again, is it possible for me to just extract the Neo Y romfs (thats already in my SD card) again with RomFS extractor? I take it I'll have to change it to .bin as trying to extract the .romfs file in the extractor just says "File is invalid binary file" or something.


Thanks!

I'm pretty sure it should work, and yes, I'm pretty sure you'll have to change the extension back to *.BIN.

 

[ZedMania]

Aight. Thanks for confirming that

No problem.

 

[ZedMania]

It.... didn't work >.< Still says "Not a valid romfs binary." The file is definitely a .bin so..... damn it. Does it have to be named "romfs.bin"? I really cant be bothered dumping everything again .__.

I don't know, I don't think I've ever used the RomFS unpacker you're using.

 

[ZedMania]

Uhh. Its the one included in the Pack Hack. "RomFS Extractor.exe". I know there's also ctrtool, but i've never used that before

Oh, that's actually what I use lol
The RomFS have to be named DecryptedRomFS.bin I think?

 

[ZedMania]

>.< It still says the same thing. Argh... thank you though

Actually, now that I think about it, the thing I'm thinking of is the RomFS unpacker in HackingToolkit.exe.

 

[ZedMania]

Ohh....... ahah well thanks, I'll go look that up now

 

[Deleted User]

It should be in that pack.

Now that I think about it... I should probably just dump the file and go through the process again. I doubt my file will work with the Toolkit either, as the extractor that I use usually doesn't have problems. Ah well. Thanks, (again xD) for the advice.
