ncchinfo.bin generation (missing headers) about 3dsconv

[ihaveamac]

looks like "Simple CIA Converter" uses an older ncchinfo.bin format which makes this somewhat more annoying to find out what went wrong.

can you try it with https://github.com/d0k3/Decrypt9WIP/blob/master/scripts/ncchinfo_gen_exh.py ?

[ihaveamac]

I only need the ncchinfo.bin it outputs, I'm pretty sure it will be valid so you don't need to test it.

It's attached. But i think the missing part in the ncchinfo.bin is the .Main.exefs_norm.xorpad?
Could that be? I used the tool without any arguments

$ python ncchinfo_gen_exh.py roms/Monster_Hunter_Ultimate.3ds

ncchinfo.bin is attached
ncchinfo_exh.zip

the ExeFS xorpad is only used by riku's tool to force regionfree, so it's not used at all by my script.

[ihaveamac]

"ncchinfo_exh.bin" is completely identical to the one generated by my script...

makes me wonder if it's something like make_cia that went wrong.

what region is the game?

[pseiler]

Hmm. I can exclude make_cia. With xorpads from simple cia convertered successfully zelda link between worlds. At the moment I use wine to convert my files. This is a good workaround for now^^

[ihaveamac]

yeah, well it does kind of bug me that my script is generating a bad CIA. no idea what's going on.

"Invalid NCCH" is usually printed if a hash check fails, in my experience. but if the exheader xorpad was invalid or something, it should have been caught (it verifies the hash of the exheader after decryption). so I'm guessing it's something wrong with building the CIA.

[ihaveamac]

hi, can you try converting a smaller rom and seeing if it works whenever you can? thanks.

[pseiler]

heyho,

Yeah I will. I will report in the next days

[ihaveamac]

is this still an issue?

[ihaveamac]

I'll go ahead and close this due to no response for a while. if it's still an issue you can re-open any time
