For a FreeShop to happen, there needs to be a CDN open for request, and pretty much the wii servers are closed, so a connection cant be done.The Scene had to create a freeshop after Nintendo disabled the purchase of Wii Points in the Wii Shop Channel, this happened on March 26, 2018.
By this I mean that we can not legally download our WiiWare or Virtual Console without the wii points, the most advisable if Nintendo disabled buying Wii Points in the Wii Shop Channel, is to create a freeshop after March 26, 2018.
Because nobody created a freeshop after March 26, 2018, where Nintendo disabled buying Wii Points in the Wii Shop Channel?
Therefore, the data for the wads, would be need to be hosted on someone computer or directly from a site and downloaded. so, its would be easier to just download the iso or the wad to the PC.
Besides, the WADS library for the wii, its quite small.
