The ticket was validated by the WMS server, it was the same way for star trek and lord of the rings. There is no way of duplicating the service unless you can somehow get the documentation from wms on how to do it and their server software. It is not a sas transaction where you just validate a ticket to give credits, it is not even done through sas, I'm pretty sure it uses wmsp to talk to wap, just like progressive information. SAS hidden little trick is that manufacturers have to pay IGT for the use of SAS, so they try and use it only for those things that are absolutely necessary, like TITO, EFT, etc. Anything else every slot manufacturer has their own protocol they use for other slot communication.
