i have loaded the official dats in romvault. marked one of the dats, right clicked on it and used the "Make Dat.." feature. after i did this on each dat seperately, i have deduped them reversed-cascaded with sabretools starting with the newest #12 release dat.
yeah i am loosing the timestamps, like in all other dats used with romvault. so, whatever
oh and in the case of playability, i can use the undeduped dat of any release and build the desired game with it, or use a d2d dat for uncompressed files (to be more accurate), like the one from darksabre76 for release 9 which delivers sha1 and md5 hashes aswell.
sadly i couldnt effort to grab the complete release #12 collection (cant build ratio with my limited uploadspeed), else i would have made a d2d for release #12.
its nice that tdc is storing the timestamps for each file, but if they would add sha1 and md5 to their dats, then it wouldnt be necessary to keep the timestamps. if i am wrong, please let me know
and if someone has the time to make a d2d for uncompressed #12, that would be sweet (looking at you darksabre76
once in six months is not so bad is it. now that sabretools has an awesome datfromdir function!
