This never purported to be a hack of the system, only to be able to read certain data from an Irdeto2 MOSC. Compare the situation with Videogard MOSCs (such as Sky Digital's card) - the system there is also not hacked, but tools exist te read some data and even in the case of the PIN to change it.
My FMCard400.exe is dated 19-sept-2001, and that version indeed only has a placeholder for the 2.1/2.2 tab (it won't activate, and I know of no way to do that). I have always assumed that the posts appearing April-2002 on other boards referred to an updated version with that tab activated. But I never bothered to chase it. So sorry, can't help.
