RemoveBodySizeCheck is a patch, created by Frostbyte. When applied, it allows you to go to the dungeon with a team whose size is more than 6 stars. However, that does not remove the check in the assembly, where Chimecho will not allow to add a team member if 6 star size restrictions will not be met. Also, that doesn't remove the check in dungeons that automatically send home team members if the sprites size is too big for the game to handle.
