-ViaxenixE.hex the file for the 24lc16 eprom
-ViaXenixEditor the eprom file editor
-Loader a file to program the eprom thru the pic

These files are adapted from the vianix files (some d2mac files)
They are adapted to be recognized by a viaccess decoder.
They use an eurocrypt M algo to decode the encrypted words. Im not sure that viaccess uses this algo.
As viacces keys are not public no test could be performed.
There is no autoupdate and no remote keyupdate on that card.
To modify the keys you have to edit the eprom with the editor.
If you have a seven byte key you must complete the key with two leading 0.

To program your wafer card you have to
Load the loader in the pic
load ViaXenixE.bin in the eprom 
load ViaXenix.hex in the pic
  
go on with your tests

These files are working files to learn more about viaccess. 
There is no waranty that they are able to decode anything
