Usage

Download the pre-compiled deb or compile it by yourself. Install the debian package on your device with Filza or by any method you prefer. Open one of the supported games and wait for the message pop-up to appear. It will say that the dumping will begin soon. Wait for the dumper to complete the process. Another pop-up will appear showing the dump result and the dump files location. After this a third pop-up will appear showing you the optional function to directly transfer the dump files to your pc.

How to transfer the dump from the device to the pc without SSH connection

The transfer process uses TCP to connect to an ip on a port. You can use netcat for example on your pc to listen on a specific port. make sure your pc and iOS device connected to the same wifi. in the dumper transfer UI type your pc ip and the port you chose. You need to open a port on your pc before clicking "transfer".

NetCat for Windows

NetCat comes with NMap and you can download it from here After you install it, make sure NMap binary folder is in your windows environment path. Now open the command line and type:

ncat -l <port> > <filename>.zip

NetCat for Linux and Mac

You can download NetCat from your terminal directly. Make sure the incomming connections are not blocked before using this.

nc -l <port> > <filename>.zip

Adding a new game to the Dumper

Follow the prototype in Tweak/src/Core/GameProfiles
You can also use the provided patterns to find GUObjectArray, GNames or NamePoolData.
