Swiv & Super Swiv fans might also be interested in checking this out:
: Swiv 3D (on Peecee)...
The Underdogs only recently added the download for this, so I can't vouch for it just yet..... but it did have a good review
Pehaps there are too many good premade ninja avatars available here....
Also heres a cheat file for Super Swiv, incase anyone wants permanent full power with ALL weapons.
That ZSNES cheat search is damn handy!
