Are there any 2P Famicom games that have AI/Computer players in place of Player 2? Thanks for any answers.
Punch-out has AI! But, it's not in place of player 2.
I think some of the bland-name sports games have AI.
For a minute I thought you were talking about someone named "AL", short for Alan.
Urban Champion is one :)
Downtown Special: Kunio-kun no Jidaigeki Dayo Zenin Shuugou!
If you don't have a second player, the computer will control a second player for you. Some of the other Kunio games may have a similar feature.
Final Fight 3 has a CO-AI. :)
Joy Mech Fight. You can have AI vs. AI matches.
V'Ball has a simple AI for player 2 that sets the ball up for you.
X-Men has a self-controlled second player, but it's neither a Famicom game nor is it intelligent.
Thank you for all of these!
Oh, and the Hummer fighting games have AI!
