The last answer was BS. The way you get past (I had trouble with this as well), is to delete any Seaside Area viruses quickly enough to get the "TrnArrow 1" chip. Then press "A" on the door.
You have to go there as tengu man and interact with the vortex
You need 200/200 standard chips.
get all 200 chips
the mark of ''s'' means that you need all standard battle chips
attack them from behind.
in undernet 2 on the oppsite side of the bbs board you must have baaten falzar/gregar and have 100 chips in your library ... enjoy gameing
There is a giant tree in the middle of Green-Area 2. Go to it and inspect it. On the back of it, hidden from your view should be a wormhole. Press A near it and Menaman will ask you if you want to jump into it. Agree. Follow the path in Undernet-Zero until you come near a tombstone / grave / monument. Inspect it. Bass will appear, though as usual. He drops a Bat Key. It unlocks a gate in Graveyard-Area. Also, at the back of Graveyard-Area is the second Bass / Forte fight. The third Bass encounter triggers when you go to Underground-Area, the place where you took a Link navi to to fight Cybeast Megaman. Step up the ramp and face two enemies: Cybeast Megaman once again and right after him, Bass. After you destroy him, he becomes a random encounter in that area.
after you defeat falzar at the end of the game i think you get the falzar seal if that was your question. hope this helped. the cyber seal is in the backround of a area thing in seaside area 2!!!:)
on the way to Central Area 3, there is a piece of green road that you cannot pass through, examine it and the key is there. Use the KeyData to open the gate to Central Area 3
The entrance to the undernet is somewhere in sky area. You have to use a couple of teleporter panels or a rush dog treat (Sold in the cyberworld of the big shower thing at Sky town).
Assuming u know how to get to the lower area of Undernet2, see the 2 dark navis looking to the right side of the screen? Just follow in an invisible path till u reach the Moonstone.
the samw way you find him in Gregar , go to the undernet zero from green area ( examine the back of the big tree in green area 2 ) move around until you find Bass and defeat him , then go to the Graveyard and defeat Bass SP ( you need all the standered chips to battle him ). if you have already done this , just go to underground 2 , go to the plateform where you battle Falzar Beast megaman . you will battle Falzar Beast megaman SP first , then you will battle Bass BX .
Well, The Batkey is for the Undernet 2, Find the gate at the upper floor, you can get the batkey from bass, all you gotta do is, go to GREEN area go to the Pc.2 then find the Biggest tree, go to the back on it then go through it, there you will need to kill BASS to get the batkey
you get it from a guy in secret area 1
