It also comes with many other features to help. You can make games harder or easier as you wish, through various mod options. 线性部分+非线性部分（非线性部分主要是激活函数，激活函数主要是Sigmoid函数） Cheat Engine is an open source development environment that’s focused on modding, or modifying single player games running under window so you can play them according to your personal preferences.
