You only need the fifa exe and patch folder. its worked like this for years. the problem is that on occasion the launcher used refuses to let you do this. Especially Steam/EA App/Epic etc.It does work, but it may only work for fifa mod manager, you take the files, copy paste them into your directory (usually a fifa23.exe, patch and data folder), then launch on fifa mod manager, and it works
At this point if you have a problem with gameplay direction then you just have to create your own mod to deal with it. Its not hard, just takes time.
