Is there a tool or some process to change Indy into another character in Emperor's Tomb? I want to play as Mei Ying and/or the Feng Twins. Is there some way to make this possible? I've tried just copy and pasting the Feng Twins files into Indy's folder (after making aback-up of Indy's files and moving them) yet when the game is loading, it crashes. So, is there any way to make this process work?
