Alright, after a few hours of work I manage to get the .fla files for characterCreation.swf and characterCreation_c.swf.

Download link is here for both: http://puu.sh/l8NeS/183024d777.zip

A lot of the code is initialized in the characterCreation_c.fla under characterCreation_c_fla/MainTimeline.cs

p1_mc, p2_mc, placeholder_mc_1, and placeholder_mc_2 are the references to the players.
