Cut and paste form a different forum:
There is new EMM being sent. I have not fully analyzed yet but the effects it has on my ROM2 activation test CAM is it sets all the $08 datatypes to type $FF

It is being sent every half hour or so and I keep activating my ROM2 and it gets desub!
I do not have full ROM2 information here so there are a couple rom calls I not familiar with. Maybe someone can disassemble better first. I can see the loop where it appears to scan the dataarea for datatypes $08-$0B and must be where it changes them to $FF. I just have not figured out what exactly makes the packet abort on subscribed CAMs.
Speculation: they could have changed the ROM2 tiers slightly and re-hit all subs during the last several months... and nobody paid attention. Or they could have similarly put in some other tier/data sent to all subs that we did not see. This packet makes invalid/clears at least all datatype $08 on CAM that do not contain this flag. It could have been worse and looped CAM - maybe they were not 100% sure of the effects of this ECM. I recommend anyone activating with ROM2 not place CAM in stream for the time being.
Well , guess Charlie and Dave are sharing notes :p
