Nimble is an Aroma setup module that patches the Nintendo Network BOSS policy list URLs on a Wii U to use Pretendo Network instead. This policy list is used to control various system functions, most notably Wara Wara Plaza. This will not do any patches besides the BOSS policy list. To connect to the rest of Pretendo Network, see Inkay
Nimble's patches are all temporary, and only applied in-memory without modifying your console. If you experience issues connecting to Nintendo Network while using Nimble, hold the ZL button on your control while booting your console to skip the patches
