How do you get the wads working in sonic robo blast 2

To get wads working you put them in the same place you put the game when you downloaded it. Next, on the title screen, press the ~ key when you arent in the game menu but still on the title screen to drop a green field in which you should type "addfile wadfile.wad." However, until you clear the game 100% (7 emeradls, all secret levels, and clearing the very hard difficulty and the secret difficutly it will then give you, earning more levels in the process) it is NOT advised to add wads because then the game becomes "modified" and you will NOT be able to earn ANY secrets or see your statistics. So clear the game first, then use wads. That is all.
