1. No-one plays on Wii U (especially BO2 since there is BOTW) because there are just Switch Soy Boys now
2. Make sure your connection type in the game select menu on BO2 is any
3. Try change your primary DNS to 8.8.8.4 and secondary to 8.8.8.4
I just tried it and still it crashes when I use WJ44's TCPGecko and also still can't inject but I think the inability to inject is because I'm not using WJ44's one
Then do you do you just launch injector file then boom bada bing, it work?
EDIT Oh Wait, don't worry finally got it working after ~3 hours also. Thank you so much!!!!! :) :) :) :) But No connect
