Shanghai EXE: Genso Network

hanghai.EXE: Genso Network is a PC fangame that crosses the gameplay of the Mega Man Battle Network series with the cast of Touhou Project and which was developed by Technodot.

It follows the adventures of ordinary student Alice Shiki and her delinquent NetNavi Shanghai.EXE as they fight the evil ROM organization in a world where Everything Is Online. Its story borrows from multiple scenarios from the entire Battle Network saga. Several Touhou characters are put in the roles of some of the original Battle Network characters.

The original developer got a C&D from Capcom and shut everything down, just before it was completed but its leaked source code was built upon and translated to English. The game has a ending, but doesn't have 100% of what was planned to had, so a group of anonymous volunteers is trying to add it to the game.
