N64 Bowser's Castle (LiC)

Mario Kart Wii Guide - N64 Bowser's Castle (Lightning Cup)

N64 Bowser's Castle

Map

1) Wheelie up.
2) A shortcut here if you have a mushroom. Just cut through the grass. If not, drift boost around the corner.
3) Watch the Thwomps, who move around and randomly drop.
4) Drift boost in the corner.
5) Drift boost again.
6) In this room, some Thwomps come up from the back of the room and float in front of you. They'll drop right in front of you, giving you just enough time to get out of the way. Prepare for that.
7) These Thwomps drop randomly as well. Time their movements to get through.
8) Use a drift boost to make the corner and wheelie to point 9.
9) Drift boost into the next room.
10) Two Thwomps slide side to side here. Don't hit them.
11) Drift boost to make the corner, but straighten out quickly so as not to fall off the bridge.
12) Drift boost into the stairs.
13) Drift outside and release the boost at point 14.
14) Wheelie to point 15.
15) Drift boost onto the bridge.
16) Drift boost all the way around to the top.
17) Wheelie across to the next gap.
18) Drift boost around and wheelie to point 1.

Miscellaneous:
Yay! The final course! A fitting end, though I think an old version of Rainbow Road would have been better (or a secret Retro cup where all the courses were all the old versions of Rainbow Road. That would be awesome.). This is still the best version of Bowser's Castle, IMO.  Watch the tight corners, as unlike the N64 version hitting a wall to straighten yourself out will slow you to a crawl.

Point 6: Dodge them when they land
