Hi /jp/, I have a friend in need of assistance with Sengoku Rance. He has installed the game fresh on a new computer, but all his old save files are lost. What is the quickest way for him to regain access to the 'second game'/If routes and the free for all mode? Would loading a save file from a copy of the game that has these things work?

I know this is not /jp/ - Tech Support, so I'll share some nice Touhou pictures in return.
