As dolphin can read the data on wii iso's (disc based games), is there any reason a format couldn't be made which separates the random padding from the data, and decrypts the data losslessly, ie reversibly? The aim being to compress the decrypted data for storage (which presumably is compressible in this state), but allowing the original iso to be recreated exactly.
Posted in off-topic because it is not properly dolphin related, or a feature request. It seems too obvious to not have been thought of, what is wrong with my reasoning?
Dolphin can compress Wii/NGC games which is actually pretty useful considering not that many games use the full disc size.
I'll give it a try. Do you know if it is 100% 1:1 reversible, or does it do something like remove random padding?
Will compressing hurt performance at all?
Thank you moosehunter. WIA doesn't do exactly what I'm thinking of, but it's close enough

It can compress and decompress ISOs losslessly, or make the compressed file even smaller by removing garbage data.
Here's some information on the tool that is used to compress the iso:

but dolphin can't read wia now can it 
(and thank god, i dont think its any good at all)
Why would you say that wia isn't any good?
cause i fail to see why it would need ANOTHER compressor or ANOTHER file format.
like .iso / .zip / .rar / .wbfs isn't enough
oorrrr; learn to scrub?

It decrypts the data to make it compressible, and also scrubs the random padding if you want. Plain iso scrubbed will not compress as well as a decrypted scrubbed file.
