How to make characters harder to defeat

[Macaulyn97]

I see in many videos some characters very hard to take down, but when I fight them myself, I take them down easily, someone told me about ai patches, how do I add them?

When you find a downloadable AI patch usually all you need to do it copy the files over the older character files.

Back the older files up first though. A lot of AI patchers make the character do impossible stuff that a human can't ever replicate and you might wanna skip back rather than keep it.
