I am tired of waiting for an IOSU hack, and finally want to play my original games online, without updating to the lastest firmware. My current setup ist: 5.3.2 WiiU, all Nintendo-Servers blocked in my routers firewall. Next steps would be: - Use WUP-Installer to spoof latest firmware - Insert game disc and play online? Simple as that? Or do I need to unblock some Servers first?
