wait... if i remember correctly the guys in revivedc used to use some linux app to relink files. i have never used it b4 though.
i remember comrade and atreyu talking about it, i also think tuxthewise had a way of relinking files too.

i think ppl have said -duplicates-once does not work properly?? idk

maybe you could create a batch file to copy the names of all files in a dir searching all sub directories and folders etc..
search for duplicates, once you know the names of duplicate files.
dummy the duplicates to 0 bytes.
then modify sort.txt each instance the duplicates are listed in sort file you point them to the directory of the non dummied file/s

that might be more work than is needed, but it would produce the same effect.
decreasing size of iso a bit to help fit cd-r, and optimizing load times maybe?
?????????????????

I remember someone using hardlinks (linux?) (program?) to make a street fighter compilation disc back in the day that would have never fit on a gd rom without linking the multiple duplicate shared files

The principle is quite simple to understand, but I can't figure out how to set it up and with what tools.
From what I understand, you must first check the files to find the identical files (they do not necessarily have the same name) and then set up the "hard link".
I looked more closely at the options of mkisofs, I did several tests but it does not work for the moment.

Sorry I don’t know much about hard links and have never used it. The wiki looks incomplete, vista is the most recent windows OS referenced. Hope these vids help (I think your using windows?). There is alot of videos on YouTube on the subject. Please let us know if you get it working on a dreamcast disc, and how if so. This could be very useful to the dreamcast community.
