I softmodded my cousin's wii with ModMii last week (explaining my inactivity) and installed Sonic 4 Episode 1 on her Wii (PAL as other regions won't work of course). It's 4.3E (with Parental Controls since she is not the only one to use it)

So I've found that for some reason she needs to enter the pin all of the time? I gave the age setting 'All Content', but the same thing happens. I know this game is a 3 or 7+, then I notice in the bottom right of the banner "ESRB Rating: Everyone with Comic Mischief"

I find that there's no direct option to enable such things, as only some inappropriate stuff for the age group will be blocked

I deliberately put the same settings for parental controls on my wii and the same thing happened

Here's my WAD installing settings (sorry I don't know how to spoiler):

WAD Manager 1.7
IOS 249
Real nand/No nand emulation
SD Installation (if that helps)

P.S. Sorry Zorlon, I've broke my promise of not making anymore Wii Modding threads by doing this
