Why does cIOS36_rev10 break Punchout?

[Tzepish]

On a wii with 4.0 system menu and homebrew channel (installed via Banner bomb exploit), Punchout loads and works perfectly. After installing cIOS36_rev10, Punchout now asks for a system update.

It was my understanding that cIOS36_rev10 leaves other IOS's untouched... is this incorrect? If not, then why would Punchout ask for a system update after installing this? Is Punchout specifically searching for IOS249 in an attempt to thwart pirates?

the Cios36 installs as 249 and 250, they dont work as "updates", but msot like add-ons ....if the game ask for updates is because you dont have the file it needs to play ( recent files are IOS38, 53,55) , you can patch the ISO, or install the files needed ONLY..
