Help with KOF2K2UM max combo

Hi, i’ve been long time KOF player, from 98 to XIV i play them all.
So my problem is really with max from 2002, i never really tried to dive into it becouse it’s really
hard so i always just pass on this mechanic.
But now i really want to learn and master it.
I can pull off some max with several character’s but Joe is really hard.
How the hell you pull this off???

Much thnx.

Here is an archive of character information:

If you click on a character, it will show you all the move information. It also has all the abbreviations explained. It is more detailed than any other source I have seen. It will take some time and it would probably be wise to learn the combo segments piece by piece. Here is Joe:
