i've spent prob 8 hours trying to get this work with no success.
I've only been able to successfully create one "Injected-Game" but when i installed it with wup installer, it was corrupt.
The other 100 times i tried to use the PC tool, i got errors at different times.
The tool gives me 7 options to inject the game into, and only 1-3 are implemented. and when I select a game to inject from with the corresponding number, the tool won't select the correct game.
At one point i entered the wrong common key, so i' went into the config file in the "JNUSTOOL" folder to correct it, but when i ran the tool again it wouldn't take the new one I edited in, it would only put the original wrong common key I entered. There's no way to correct the common key within the tool, so I had to start with a clean version of the tool.
I think it's great that tools like this are created for common users like me, but I've now given up trying to use it because it was too difficult.
