Yeah that would solve the issue, you may see some universal method on future Loadiine releases. But this would require you make significant mods to your entire game library manually, and would break these games if ever you can repack them into NUS format again for IOSU installation.No, i guess he was thinking about repacking extracted files in a new container.
This would result in one single file which won't be bigger than the extracted files
(actually it would be smaller, less overhead from the clustersize)
You'd end up with a massive library of modded games that will only run in Loadiine. Which may be a pain if ever better hacks come in the future.
