Tootsville IV
From Tootsville Wiki-Wiki
The conversion from Tootsville III was code-named (in its entirety) Project Quicksilver.
Code-named Project Osiris for the server and Project Persephone for the Flash client program, Tootsville IV was the last version of Res Interactive's Tootsville produced by Res Interactive before they went out of business.
Much of that program was lost or destroyed in the process of Res's dissolution.
Legacy Players are welcome here, though!
The server program for Tootsville IV was written by BRFennPocock, and the front-end (Persephone) was largely written by Robert Dawson and later expanded by BlackDaddyNerd.
