About the maximum level.

A trainer is something similar, but for me, this method isn't very intuitive, to be honest. Although, I wouldn't mind more details in a private message. Editing bytes is not the same. I need to add something. When I add, all the addresses in the file shift... Ideally, I'd like to create an editor that tracks the addition of bytes and corrects the addresses; that would be perfect. But I haven't figured out a simple algorithm for how to do that; it's very difficult to distinguish between address bytes and code bytes... Unless you start tracking this from the very beginning of the file, but then you'd have to write a full disassembler, which is not ideal.
