I've discovered you can click REMAX in Forge to advance each chapter by 100 stages till you reach whatever number of stages where the girl is to finish the chapter if you end up not beating a boss then you'll have to finish that remax and another remax to get the girl chapter 4's a pain don't forget to use your BOSS fighting girls in your line up. The fifth chapter will not unlock I don't think till all 4 chapters are finished. Plus anything use to speed up the process chapters 1 and 2 Mojo Robot and Perks are useless they'll crash your browser info is just to fast can't keep up. I've been using just the LVL MAX upping the girls as the Yemens goes up. Chapter 3 and 4 your gonna need them.
