Unable to extract/open OBB file for Final Fantasy Dimension 2

[viviboy70]

Try this
https://github.com/veronicakulikova/obbd...bdown2.jar
(Requires Java 8)
Usage:

Code:

java -jar obbdown2.jar

Or this (if you don't have Java)
https://github.com/veronicakulikova/obbd...bbDown.zip
Usage:

Code:

ObbDown.exe <obbfile> <outdir>
Or
Drag and drop obb file onto ObbDown.exe in File Explorer

Thank you for showing me this!!
I'm not sure if I'm using this correctly.
I tried to drag and drop but got this message: 
IO Exception occurred. Details:
java.io.IOException: missing boot sector signature.

When I ran ObbDown using the Java codes I got this error (see below)

Error: A JNI error has occurred, please check your installation and try again
