When I put the custom story in the stories folder and I openn the game I can only choose between Tutorial and Normal Game
simple thing first: try scrolling down. the drop-down menu that you get when selecting a story can scroll to show more stories.
if you're playin 0.8.5, you should also have "slumber party at madison's" and "date night with brittney" included by default. if not, your firewall might be blocking the game from accessing the internet. you can tell if your firewall is blocking the game if you see red text telling you that the game could not download the latest story files from the server.
even if your firewall is blocking the game, the custom story should still be listed as long as you're doing it right.
make sure the custom story has its own folder in the /stories/ folder.
the custom story folder should include the .story file, as well as all of the character files that came with the custom story.
make sure that the .story file and the folder that its in have the same name.
make sure that the custom story
isn't still zipped up.
