God Eater Resurrection

Post by Katsu »

Hello,

I am currently using this http://aluigi.altervista.org/bms/god_eater_2.bms to extract files from God Eater Resurrection. It worked good for the Japanese version of the game, however it is not working for the english counterpart

I get this error http://prntscr.com/c2rdgy when trying to extract the files. The file is a package.rdp, any help would be greatly appreciated! :D

package.rdp of the english version is about 500mb larger than japanese one and is 2.4gb.

Sorry if my english is hard to understand, thank you

From a first look of the screenshot everything seems correct in the sense that offset + size matches the next aligned offset, but the 12% of coverage means that something is wrong.
Can you upload a sample?
You can generate 2 files to upload from package.rdp by using this script:

I did not expect such a quick reply! Hopefully you will be able to help :o

I ran the script and got these two files attached

ありがとう!

I can also provide the package.rdp my friend uploaded if you want, it is however a big file

It's strange because the script works correctly with the splitted file, it starts from offset 0x800 (which is correct) and handles all the files at correct offset/size.

Even if the format is not easy and there is no index file (the script is a sort of scanner) everything seems to work correctly, there is one thing to update which is the compression but currently I don't see other problems and I don't know why it gives only 12%.

In the meantime I have fixed the blz4 compression with script 0.1.1 and probably also something else.

Let's do the following, try the new script and let me know what's the coverage percentage you get at the end of the extraction (don't worry about possible errors).

I have downloaded the new script and ran it, it gets to 15% now, still crashes at the same file though :(

My friend also said it was ok to provide link to full package.rdp

Ok, the version 0.2 of the script seems to work correctly and it extracts tons of files without errors.
The problem was caused by a number indicating the number of set of files (don't ask me what it means because I don't know it) that was ever at 1 except in some locations.
Try it :)

That seems to have done it, thank you very much! I can finally get some sleep as the sun is rising here lol!

I will let you know how everything goes when the extraction finishes, hopefully an undub can be done :)

Is there any way to set the default as yes instead of no when reimporting files? I have multiple audio files larger than the original as I batch overwrited the two game files.

Thanks!

If they are larget than the original then you should NEVER force any reimporting.
Anyway there is the -Y command-line option in quickbms that allows to answer yes to any question but that's not valid for forcing reimporting as far as I remember (on purpose!)

Yes, I tried - Y but it did not work like you said. The yes option for importing just skips the file, it was the force command that actually forced the import? I wanted a version that put default to skip, instead of closing the process. Hope that makes sense

Thanks you!

Script 0.2.2.

It wasn't a bug in the script, just a field that was set to zero and was necessary to "reset" it to one to work correctly.

when reimporting , do i have to make specific folder for each file ?
or it just auto import to the same folder ?

package.rdp -> D:\12000(folder)\file1.txt

D:\patch\12000\file1.txt(edited) , then choose patch folder to import ?

or just D:\patch\file1.txt(edited) and quickbms will move it to 12000 folder

For reimporting you have to do the same steps and selections you did for extraction.
The only difference is using reimport.bat instead of quickbms.exe

Hi, alugi. Could you adjust your script for unpacking *.pres files? I mean standalone. (Is it right expression?)

Uhm.. I told you that I want to make repacking script.
In order to do that I need some simple form of bms script for *.pres files.

It already exists :D
Check the function EXTRACT_PRES in the script.
