I have both rom set .161 and chd set .161. I know how to update the rom set and chd set, but my question is this.... I have the rom update packs from this site, does the update pack include update for chd? I was told there is a separate update pack for chd in general. If this is true I looked everywhere and can not find such a thing, where can I find it in particular? So another wards if I have the update pack .161-.162 from here and I update my rom set .161 to .162, do I use the same update pack to update my .161 chd set?
