Loadiine works very well if using an SSD and MochaFat32.
GC/Wii/WiiU All on one SSD no need to install via WupInstaller.
Have access and ease of use modding and swapping files via PC otherwise FTP is required for accessing and from experience FTPING Always OVERWRITE never DELETE.
So Loadiine and USBLoaderGX and MochaFat32 and an 1TB SSD with Y Splitter USB3.
You however need to use a special build and there is a Forwarder available too.
But choice is yours Sunnyboy! lol
