just a word of clarification (to avoid misunderstandings) -
the term "FreeCAM" was introduced when the emulator function and facility for entering/editing internally stored Irdeto plainkeys was built into the CAM's firmware. So to use the "FreeCAM" as it was originally intended, you need to turn ON the EMUlator (via the CAM's "goodies" menu).
With the EMU=ON, the CAM is only using its internally stored keys and they are only Iredeto plainkeys. No other encryption system is supported in that mode (well, alright, Betacrypt is too, since that is essentially the same as Irdeto and uses the same key structure).
If you turn the EMU OFF then the CAM gets its keys from an inserted card - just like any other kind of CI CAM.
The FreeCAM2 variant of the firmware was introduced to support multiple encryption systems in that (emo off) mode. With a FreeCAM2 and a suitably programmed card of the right type it can handle the following: Irdeto/Betacrypt, Mediaguard ("seca"), Viaccess, TPS-Crypt (variant of Viaccess) and Nagravision. The card-type (namely the actual internal chipset) and the card software ("hexes") that you need depend on the encryption systems you're going after. Two types support the mentioned six simultaneously - these are the so-called DS9 card (DS9 software loaded on a "silver" card) and the 6-in-1 Funcard. For each respective card-type there are a number of different variants of the software/hexes that you can use, some tweaked for specific receivers. You should use one that is specifically made for and tested with your type of receiver/CAM.
The FreeCAM also supports normal goldwfers and there are software/hex files available for single or multiple (pairs of) encryption systems. For example, the Irvito files allow viaccess reception on your Irdeto FreeCAM.
