Are there any tools like REDitor for 2K18 any more?

more than players info. which could also edit the whole database (including the text of teams, courts or something more),

It's mostly down to trainers and cheat engine these days. Before he joined the team at Visual Concepts, Vlad had a look at the roster files in NBA 2K15, and said they were basically impossible to decode. Presumably, the situation isn't much different now. That's why we don't have the easy-to-use tools like we used to. That, and we don't have as many programmers in the community these days.
