the wii u has to format the hhd into order for it to store things onto it, meaning you had to have had a second hhd for wii and gamecube. With the injector, it allows you to inject wii and gamecube games into icons onto the system and is stored on the wii u hhd.
You need CFW in order to inject Wii and Wii U games.
Edit: There seems to be a way for Wii USB Helper to still work. I highly recommend this because of its gui. https://www.reddit.com/r/CemuPiracy/comments/8gj8z8/workaround_download_and_run_wii_u_usb_helper/
Wrong, number 1, it is possible to have Wii, gc, and Wii u with this tool https://gbatemp.net/threads/release-wiivc-injector-script-gc-wii-homebrew-support.483577/
Yes, you are good. However, if your WiiU is hacked, you can use WupHax so you don't need a game dics. https://gbatemp.net/threads/wuphax-v1-1-hacking-vwii-from-wiiu-mode.446786/
@SylverReZ I've never used a disposable, seems like a waste. kinda cool idea tho. It would be nice to have vape built in to a cell phone even. "The iVape"
only ps5 updated to latest firmware can go on psn, jailbroken ones just don't use psn or they risk getting flagged or banned, altho spouting profanity in online play alredy does that
