Import Robot to Robocode
Welcome to the RoboWiki!
It's also interesting that you say you imported the robot into Robocode, but it didn't appear on the list of robots. I assume that you used the "Import downloaded robot" feature of Robocode. I might've had the same problem with it. Try downloading this robot and then see if using the Robocode import feature works. If it doesn't, just copy the .jar file into the robot directory, and Robocode should recognize it.
This thread isn't really appropriate for the main page discussion; if you don't mind, I'll move it to User talk:Cristiancompany.
Welcome again and good luck!
