Getting the Nebula CD
First of all you need 10,000 Zenny and to be past the part where you fight ShadeMan in the ToyRoboComp and then you must find Django the solar Boy in Undernet 4 he will tell you about ShadeMan and how they fought and he needs the S. Sensor to destroy him.
Then you must go to Undernet 2 Area ( you'll have to go to the entrance of the area) (it's easier to logout and start form the NupopoComp in Netfrica) and find a purple HealNavi he will be complaining about how somebody stole his treasure and it was as shiny as the sun he will say the guy that stole it is in Undernet 6. Then you will have to go to Undernet 6 and look for a black HealNavi he will say that he'll give you the S. Sensor only for 10,000 Zenny buy it.
(be sure to have the 10,000 zenny I told you about earlier) Then you have to go back to Undernet 4 Area and go to Django and give him the S. Sensor (it won't work if Lan isn't in a place with sunlight meaning you have to access the Undernet from the NupopoComp no questions asked).
You will see a short clip of Megaman and Django destroying ShadeMan then when every thing is done you want to look inside the coffin and there will be the Nebula CD now you can unlock those skull gates with the blue mystery data inside. Congratulations I hope you find all the secrets.
