Neo Geo CD and Sega CD versions reach beta.

In a one player game, the second frog is controlled by a simple AI. It's able to compete fairly well. It probably needs more tweaking. It's implemented using a finite state machine.

This brings the game to the beta stage. This will not be a feature complete beta, as I would still like to add a few more features before it's release at the CGE and VGXPO being held on August 20-21.
