Honestly guys, I'm to lazy to finish making the application and rather release this to you guys instead. The archive will contain three applications and a text document. The text document will explain how to use the console applications and other stuff as well.
Also, I will give you some information that will help you mod your saves a lot quicker then usual. If you search "inventory/" you will come up with different types of strings that have to do with "inventory/". What you need to do is look for something similar into your inventory on the game. So for example it could look like this "inventory/throwable/explosivegerenade", then look to the right of the string and then look at the bytes. for example It could look like this "00 00 00 04" on the left side of your hex editor.; this displays how much you have. Last thing I'd like to explain to you would be how to modify your money on Rage. Again this would follow the same steps that I just provided. Search this up "inventory/currency/currency_unit". Look to the right and look at the bytes.
If you guys would like to modify your jump hieght or speed. Which I think is possible. I never tested it out to be honest but search one of the following below.
jumpImpulse =
speed =
Note that there is possibly other stuff you can do within this save. So please go right ahead and mod your heart out.
