I don't know rhe vx-mini, but is it one with a built-in loader?Don't forget that you can only access the eeprom on a wafer card by using the through-PIC method - i.e. by first programming the PIC with a special loader program. See the wafer How-to/FAQ in the smartcards forum for more details.
Some programmers do this automatically (i.e. when you execute the "program eeprom" function, the device itself automatically starts off by placing a loader in the pic. But most programmers DON'T do this - you have to do it by hand.
Also bear in mind that not all loaders work with all devices. And there are so many different varieties/versions of loader. I've picked up some 40 different ones from the various hex/bin filesets distributed over the years, and less than half of them work with my particular pc/programmer. It's a case of trial and error, and when you get one that works 100% - SAVE IT and always use it in the future in preference to any loader distributed with the actual files you are programming. The same loader can be used for all encryption systems - so you don't need a distinct Irdeto loader and a distinct Mediaguard loader (or whatever).
You say you loaded wallbanger onto the eeprom. What do you mean? Wallbanger is a smartcard emulator that runs on a PC, not a thing you load onto wafers.
The 24LC16 and 24C16 chips are functioanlly the same. The "L" notation indicates low-power-consumption. Files that are ok for one are ok for the other.
Does this help?
