after analizing, I have came to the conclusion that it is only the 'Ntreev Game Card' that qualifies. No other Game Card will work. Seeing also that I have only seen this Game Card once in full (saw it on a tag at the recharge menu), and the fact that I live at Canada, I can't test it out or find out the denominations of that game card.
In conclusion, Sorry for those who live outside the US and/or those who's blockbusters dont' have it yet. You either must give up/wait on them. Though I'm quite ticked off that this only applies to US stores, I'm used to it.
