Dude..this is amazing. And weird how effective they all are in the game. It can be really freaking challenging at the same time to, which is you know weird.

Eh, not much new info at all here. It's pretty obvious after playing games for such a long time how the AI's of certain games work and all, Nya~.

Now for the Super Mario Bros 2 USA AI's, a work in progress, because i don't understand what some of the AI's are, I haven't seen some of the enemies, and I don't know some of the enemy names so correct me if I am wrong, so here is what I have.

Shy Guy Pink AI: Walk left and right but don't walk off cliffs.
Shy Guy Red AI: Same as pink but can walk off cliffs.
Ninji AI #1: Stand in one spot, and jump low.
Ninji AI #2: Only difference is that it chases you instead of standing in a spot.
Bird on Magic Carpet AI: Fly left and right above you for a few seconds before swooping down on you, and repeats.
Pink Birdo AI: Just spit eggs.
Red Birdo AI: Spit a little fire, but more eggs.
Green Birdo AI: Always spit fire.
King Wart (final boss) AI: Launch bubbles out of his mouth, and occasionly opens his mouth.
Porcupo AI: Maybe the same as the The red shy guy, I don't know.
Beezo AI: Fly at you at a angle.
Phanto Mask AI: Chase you in a annoying pattern, doesn't stop chasing until you drop the key or enter a door with it or without.
Pink Bird (Not birdo, I don't know the name, a ground enemy) AI: Bounce very small twice, then a bigger bounce, repeats.
Flurry AI: Slide on ice, and chases you.
Sniffet AI: Shot cannon balls out his nose if you get near it.
