Hello all, I generally use ZIP for most of my stuff and it works fine; it's recognizable by both Romcenter and other things. The one thing I have run into is compressing Wii ISOs. In the case of Wii U I have used 7Zip with good success (decent compression and it is recognized by Romcenter). For whatever reason Wii ISOs will not compress using 7Zip. Does anyone have any suggestions on how to compress Wii ISOs into a format that Romcenter would recognize? Side note, RAR5 actually does better compress with Wii U then 7Zip, but I understand that it won't be supported in Romcenter due to licensing.
