How do you get to the undernet?

Your trying to get into the undernet huh, you must be on the mission where you have to get protoman. First you will need a Key Item called the "C-Slider"
To get the C-Slider you must buy the parts for 3000 zenny each. The first piece is in Town Area2, go into the teleporter that is closest to the exit of town area2 go under the platforms talk to a pink navi he will say "wanna buy this junk board it's from sharo" something like that and buy it. The next one is in town area3, but to get to this one you need to go into park area1 look for a piece of the floor thats cracked go up and turn right look for a green navi that moves up and down talk to him and get the piece. The last one is in yumland, ill give you directions for this one. When you get off the bridge follow the green path until you see a path that leads left, and one that goes down all wavey.Go down the wavey path press "A" under the bridge until you speak to a purple navi, buy the piece from him. You have all three pieces go into sharo area. Go left, up, left,up.look for an area with a door.pay 500 zennys to get in you will see an orange navi talk to her and she will make you a C-Slider. If she dosen't make you it talk to the navi by the undernet, to get to the undernet go into netfrica area try to find your way to a green navi and mr.prog follow the blue path. You will be in sharo area talk to the navi by the narrow line he will say" Beyond here is the darkest place on the Net...the Undernet. Hope this helps sorry for writing a lot :P
