You can use SLADE to edit myhouse.pk3.

You need to edit the MAPINFO file.

And replace the first part of it with this:

gameinfo

{

  //PlayerClasses = "ActionPlayer"

  //AddEventHandlers = "ChainsawRemover"

  AddEventHandlers = "BillboarderHandler"

}

Essentially, just comment out the lines PlayerClasses = "ActionPlayer" and AddEventHandlers = "ChainsawRemover". This will let you start the two .pk3's together. I am not sure if this breaks anything though. Don't get too excited, it probably WILL break things!
