PokeDex v 2.0 First you need to have a Java runtime/sd kit installed. Get this from http://java.sun.com You need to set your paths, and then run java -jar PokeDex.jar At the command prompt. Case matters. If you are really good, you can make a shortcut to this by putting "%javapath&\bin\java -jar PokeDex.jar" As the program to run, where %javapath% is the path to the installed java kit. You should also set the start in folder to wherever you keep the *.jar and *.pkmn files.
