CHD Set Update Help

[FrizzleFried]

What is the most efficient way to update an old CHD set?  I have a CHD set from .154 I would like to update to current.  I really would prefer NOT to have to re-download the 300GB or so I already have here... aside from locating and downloading the incremental CHD updates (some 50 between then and now) ... is there another way I can do this?  Could I torrent the latest full set and just aim the download toward my already established set?  Would that "fill in" the missing ones or do the CHDs change between versions?

you'd point the torrent at the saved folder.
Verify everything is named the same.
Delete any old CHDs that have different files sizes than the new ones.

I guess I have to start the Torrent to determine the sizes of each folder and manually go through each to determine if my local version matches?

Also... does anyone have a list of CHD's that actually WORK in some fashion?  Why download a ton of CHD's that don't even work if you don't have to?

when you start the torrent it should show a file list along with sizes before you have to download anything.   Only CHDs I have are blitz, showtime, ki1, ki2, and gauntlet DL

Welp... this has turned in to a cluster-F...

I attempt to torrent to the folder with my .151 CHDs... it does it's check and finds 91%... great... but I notice that individual CHDs are at various degree of completeness... and then I get some strange I/O error in windows that hoses my torrent and I'm back at 0kps... and refuses to download.

>sigh<

It sucks having a metered connection... 300GB/mo and the damn full CHD torrent is like 450GB (non-software version which I assume is the version that includes computer stuff?).

Even a full set of WORKING CHD's comes in at about 90GB... 1/3 of my damn monthly quota.

Damn I hate crap internet.
