Scrubbed images are bad dumps. A lot of bad dumps, also for cartridge systems, work well on emulators and /or backup on real machine, but they are bad. Many other bad dumps don't work well or don't work at all:
1) Many scrubbed GC games don't work because of streaming.
2) Some scrubbed Wii games don't work until some IOS are updated for them (this is a hack!)
3) Some scrubbed xbox1 don't work
4) Scrubbed xbox360 will never work (I don't know if they'll do on jtagged)
Redump was born to preserve 1:1 images or at least as near as we can. It's like you want to ask members if we want to preserve bad dumps. I hope nobody will never mind to preserve those bad dumps here, this is an example of what I was talking in another discussion.
I know new systems discs are quite big to archive but nobody force you to preserve them this way, it was only forced by Redump quality. In the future somedody might ask "why don't we preserve audio tracks in mp3 format?".
I'd like to remember that Redump is a preservation website and not a warez website.
