I think that as a less technically savvy reader, it's difficult to understand, based solely on your code snippets, what you intend to achieve with such a new emulation, or what the result of this new project should look like? For example, what do you mean by "I wanted to create a more refined and realistic emulation"? A new (King 2.61) engine or only an adjustment?
Some further information would be helpful
