infact one of our project torrent have a dat file with packiso's CRC for quick renaming, and we plan to release the dat with every update from now on, which should solve the time issue in renaming those sets.
for people that would get those images elsewhere and then compress accordingly - with PackIso
to join in torrent at higher position?
but the thing is - there aren't alot of those people, as i understand it.
majority won't be bothered with renaming themselves - they'll take what is given.

so, imho, if somebody feels like recompressing and reuploading, like xenogears i suspect may (to .zip/.rar)
it wouldn't do any harm - the more there are those torrents - better
one enforced set without alternatives wouldn't be good
even though i think .zip or .rar particularly aren't rational - still if somebody feels different about it - it won't harm
(well, not any more than any torrent based on redump.org .dats at current state
i see a general problem with names, i think they're terribly wrong,
hence in torrents also and anything else derived from them
but that is a concern of redump.org crew)

afterwards to maintain names in sync with updates made at redump.org it would be enough to compare .dat files (redump's):
one taken when set was made, and current - ther's no need to rescan whole set every time, imho
(and to produce alternative .dats for that reason)
when it's uploaded it's locked to redump.org @certain point in time (like a snapshot),
so you can say this torrent is a subset of that .dat
when you see CRCs of some title change from .dat to .dat - you know this CD should be updated
when same CRCs belong to different title now - it was renamed then
and new records would manifest as new titles with new CRCs
that's all managment there is, and it is a concern solely of person maintaining torrent, not everyone downloading it, as i see it
i don't really see application for .dat indexing compressed files

I see what u are saying, and that why we also provide a change list which list games which has been changed since the last update, thou at this moment all this is done manually, and a automated solution would be great. the compressed crc dat files are for peoples like me who have miss couple of updates and thus can use that dat to quickly find which games need to be updated

about namings of the games, thou i am a big fan of serial # coz thats what i have been using since Psx_renamer days, but i do agree, we need to somehow provide the info what version of a game a said dump is.

i personally don't worry how long a game name is as long as it provides the following info

GameName-region-Language-version-edition-serial

PS: i need patches for few PSX Asia games dumped by u, and maybe few tracks/full images, could u provide that somehow.

about equal to archive size, i guess, which would be huge
I will go back on this later.
I suggested this for stuff like Gamecube that have no better compression with 7z.
If images will be setted to same date and compressed with same version of winrar and same settings you'll have the same of packps2, or not?
