It's not really a problem "knowing" how to patch them, obviously replacing files is easy...but the problem I'm having is knowing which patches are out of date and which ones are more recent.

I've been looking at Dr. Invincible's page and he's got at least 3 patches for various characters for A.I. updates.  I tried patching a few characters, but what happened led to either some weird bugs with the character, or a fatal error, or something else.  Here's a few issues:

A.B.A. Patch:
Seems to replicate A.B.A. in idle standing animation, but the a.i. still works...it's weird.  Also an A.B.A I used earlier had a weird glitch where it was in permanent Berserk mode with awesome A.I., but no matter what it did, it couldn't do damage or kill you.  It was a Black ABA mode of sorts.

I-no Patch:
Seems there are sprites missing, or I get a fatal error.


Kliff Patch:
Fatal error after patching.

May:
Fatal error either for XX May or AC May.

To avoid confusion, I'm trying to avoid "hybrid characters" right now, like Chipp++ or Hybrid Testament or Slayer.  And ideally I'd like to patch every character up to AC level if possible, with decent A.I.

I hope someone can help.  Thanks.
