oh I missed the bluray part.
dolphin scrubs wii isos because it *has* to. Otherwise there would be little to no compression at all (because the entire image is encrypted).
There are many ways to decrease file sizes, all relating to being able to have special cases, such as:
decrypting wii images along with scrubbing
decompressing common file types on the gc/wii images in order to let our compressor do it better and transparently recompressing it into the game's format when read.
other things such as removing "unneeded" partitions on wii images.
give up on streaming formats and force the decompressor to load the entire image in ram.
All of these options have significant run-time performance and/or data "safety" issues.
This comes down to us storing as much of the original content as possible, in a manner fit for streaming decompression.
Since ALL the gamecube games produced can fit comfortably on a single modern hard drive, the minimal space savings offered by possibly loosing important data forever is just not worth it.
