[Feature request] Recreate Redump-matching isos with Repackinator #45

Closed awsms closed 1 year ago

awsms commented 1 year ago

Would it be possible to recreate an .iso that matches the checksums of redump, after scrubbing a redump iso?

Natetronn commented 1 year ago

Not possible, that I'm aware of, they are different files at that point and will therefore have different checksum. A couple notes from the docs that will hopefully make it clear why the file has changed:

Scrub: is selected by default. This will replace the padding with zeros, for greater compression. de-selecting will simply split ISO for Xbox FATX file system during processing.

Trim Scrub: will remove all unused data at the end of data partition. Similar to XISO

I'll leave this open for now, just in case I'm wrong and the geniuses around here know better, however.

I know that NGC & Wii redump-verified isos can be unscrubbed with NKit after scrubbing (and they will rematch the original iso), so maybe it'd be possible for Xbox games too? If this is definitely not achievable with Repackinator, I'd love to hear some alternative software recommendations. This would be a game changer for all the Xbox isos data hoarders out there!

The difference is that Xbox uses random padding. Unless you store all the padding as extra files you won't be able to re-create to the original. And at that point you might as well just store the entire file.

Thanks @zappepappe for the support. Issue will now be closed.
