[holyluigi]

After beeing able to extract the romfs I have tons of .arc files and don't know how to open them.
Would be glad if someone could help me ^^

Try using "Every File Explorer." https://gbatemp.net/threads/release-every-file-explorer.373615/

Oh cool Thx for that. I already tried various programs (including EFE) already but all of them said "nope"
Notify me when you had the time to upload this or just post the link in here. I have nothing more to do in MH4U so I wanted to go nuts on some other stuff ^^ (Waiting for MHX release and my import to arrive somewhere in december XD)

yee.. any idea on the texture files tho?

and the script even works on super street fighter IV 3D edition too... but it doesnt seem to unpack every .mod file (especially the stages)

How interesting. I've been working on a few tools for Ace Attorney Dual Destinies which might apply for other Capcom games as well. I've made an .ARC extractor and a TEX to PNG exporter.

The tools are Ruby-scripts right now and they are not polished in any way. I can upload them for you if you want. Beware that I haven't implemented any packing functionality just yet, since I've been mostly interested in unpacking the formats at the moment. I'm actually planning on making a real tool for TEX files, but I just finished documenting the format, so I haven't started on that yet.

i'd love a tex to png honestly!! there's also some .tex files in smash3ds also.. would it unpack those as well? just a bit curious xP

I have no idea. I haven't taken a look at the .tex files from Super Smash Bros. 3DS. I have only been working on the TEX files found in Ace Attorney: Dual Destinies. However, if the TEX files in Smash Bros. uses the same format as the TEX files in Ace Attorney: Dual Destinies, then sure, it would most likely work. I don't know how likely it is that they are the same, since the same extension doesn't mean the same format. ARC is a good example of this. I don't know how many ARC formats I've seen up until now and every format has been different.

Btw, I borrowed my brother's copy of MH3U for 3DS to see if I can use my tools on the files in that game.

 

[Demonslayerx8]

hmm i see... want me to send u some examples?

 

[Gryphon93]

I own a copy of Super Smash Bros. 3DS so I might take a look at it later, as long as it is possible to dump the RomFS with braindump.

 

[Demonslayerx8]

hah alright... and should be, but ur also gonna have to unpack the .dt file too.. which is located somewhere on this site

 

[Gryphon93]

You can send a PM with a TEX file from Smash if you want me to take a quick look. I can determine whether or not the format is the same as the TEX files from Ace Attorney: Dual Destinies.

No, EFE doesn't support Capcom's arc.

I could extract them. With a hex editor you can see all the texts.

 

[Gryphon93]

I've now checked some of the .tex files in MH3U and (unsurprisingly) they use the same format as Ace Attorney: Dual Destinies. I'm happy that there are a lot of .tex files that include more information on the last bit of the format that I haven't really figured out yet. Hopefully I'll be able to work out the information and complete the documentation.

I'll upload what I have made up until now soon. The tools are not well documented and optimized because I used them to analyze the format. I've plans on creating a "real" tool for .tex files soon, but no promises.
