ROM Hack Question "Error: Section 0 is corrupted" despite full keyset?

einfuchsdrache · Jun 26, 2018

Hi, I'm trying to unpack a dump of the new BlazBlue game, but it gives me an error when I try to unpack the big .nca from the secure directory. I am absolutely certain that I have a full Keyset, but I still get said error. Is this a known problem? Or could there be new, undumped keys?

EDIT: I just saw that HACTool can report which Master Key Version is required and it's Master Key 3.

EDIT 2: Apparently the hactool build I had didn't like the .nca. It worked fine with the latest official release.

there are only 3 things that could be wrong, either some keys are missing/incorrect, the dump is bad or you use the wrong command. I had no issue with this game and a full stack of keys.

But if it was a bad dump, wouldn't it tell me that there is a problem with the XCI when I get the NCA's from it? Commands I used are "hactool.exe -k keys.txt --romfsdir=romfs --exefsdir=exefs (nca).nca". Keyset is the one from maxconsole.

newer games require newer master keys dont think the guide is updated for newer keys though

I mentioned this in OP, hactool can tell you which masterkey revision is needed. It's revision 3 which has been out for a while.

Try "hactool -k keys.txt -t nca --romfs=romfs.bin --exefsdir=exefs (nca).nca"

I can try that, but isn't the default file input type for hactool nca? Also I'm curious, did you use the BBB Dump or a private dump?

Not sure about that, i always set the value to the format I want to extract. And I used the BBB dump.

OK I've tried manually setting the input type, still didn't work. However, now hactool is crashing everytime it tries to unpack the romfs.

yes but as far as I know you would have to find it online somewhere baucaseim pretty sure the keys.py is not updated to extract newer keys

I'm not extracting the keys myself.

definitely weird, i just extracted the file again (same filesize) and it worked like a charm. then I'm gonna stick to the keys part, as I'm not sure which keys are in the maxconsole dump.

join the discord if you can (https://discordapp.com/invite/NbfhykM), we can talk freer there.
