AC4400CW KCSM (Auto Numbers)

The artwork and research behind this project was completely done by Jose Uribe (Monchito5).
The editing of the .bin files was done by me (Jonasson Bacon).

Note: This version is made to use with the patch of the CP-Golden Beaver AC4400CW from Searchlight Simulations.

The original version of the repaint for the patch is available on the Monchito5 Facebook page, link below:

That is bad, but unfortunately i cannot help you out then, i am not aware about the differences between the Searchlight and the Steam version of this loco, and i wouldn´t be happy with editing 83 bin files again.

That can happen when u own the Steam store version of this loco, it is not compatible sadly, This repaint only works with the Searchlight Store version.

For some reason this does not work with How do I fix that. No horn and monitor is bugged.

Yes im aware of that, but in the moment i dont have the time to fix that bc that would mean to set up the whole loco again. You have to stay on version in order to use this repaint, sorry.

Which file in the "Default" file is the "serial.dat" and the "key.dat" files? Because I can't find them.
