Can the creater of PackPS2, edit the program to be made to compress things besides ISO?  It just 7z the file right?  Should work for anything?  Hopefully someone can help me

i will add the remaining image format on Monday, i won't be going to office before that and the source code is on my office PC

I compiled p7zip 4.53 on a OpenBSD system (Pentium III 800MHz), used "touch -t 197912310900.00" on the file and compressed it with "7za a file.7z file.ecm"; then I used packiso on a WinXP SP3 system (AMD Sempron 3000+) on the same file.
Though the 7z size was the same on both machines, their md5 was different.

It's a shame that the guys who did torrentzip have no intention of doing a torrent7z...

The problem probably is with time stamp and file atributes, as rmdtrasht.exe set the date to 1980/01/01 01:00.00 (i think it's (GMt) Greenwitch Mean Time) and removes all file atributes. Of course date must be set for: created, modified and accessed time stamps.

Though the 7z size was the same on both machines, their md5 was different.

Can you do a binary compare to see how different those 2 files are? Maybe there is only a difference in the file header or the whole data stream is different.

If someday Daemon Tools will support compressed audio, this would be the perfect solution.

It has been discussed several times, but sadly they are not so open minded for new ways....

...but this could happen with torrentzip aswell

No, it couldn't
Unless there was an error of course.

But seriously, from what I know of torrentzip, it was designed specifically to make identical results regardless of machine/OS (most probably by using integers only).

I thought the same could be done with 7zip, so when you said that PackISO got identical results on different machines I thought this was the case.

Those people should try it instead of praying.

Oh thanks for this info, didn't knew that. So this mean that if i used the ultra setting instead of default in Packps2, it will still make the same Archives?

It will make the same archives when you use the same settings. Compressing with 7z ultra leads of course to higher compression vs. the normal 7z compression (because of Increased dictionary size). But every computer has to have enough resources to use such a large dictionary, else compression outcome might differ (when there is extensive paging for example).
Also you could use other advanced settings to improve compression.

Well, I am not completely sure (I did not look at the source of 7-zip), but so far packISO did work for many people on many different computers. Unless someone comes with an example that the file created is different, it stands as is (it's not a mathematical proof, but a natural ... it is right until someone disproves it). Of course everyone has to use the same 7-zip version.

the file extension should be iso for it to work. if you have more then one image, u can either put them in a single folder or in subfolders and it will compress them all.

Actually No, it will not create same Archive on different PCs, if you look into your Packiso folder, there will be a file called RMDtrach.exe (or somewhat similar name), that exe it what make it possible to get same images on different PC.

Well, yes, i forgot rmdtrash. What is does is zeroing the created/modified/accessed times.
Still 7za will create exactly the same files on different machines with exactly (Which means file times are identical, too) the same source files.
