Hello guys,
I've managed to dump a vending machine key and I'm trying to play with the credits now.
As you can see in the screenshot I have one dump with 300 cents and one dump with 400 cents.
The thing is that not only the value block changes but also some other value which may be a checksum I think.
Has anyone seen this yet and knows a solution for how to calculate this "checksum"?
