Hi, I have made no changes to the default configuration of CFG USBLoader.
I also removed IOS 202/222/223/224, made no difference, games still starts, but i bail when it says it wants the nunchuck connected.
Maybe you have a bad dump ?
Windows 7 shows it at 7.92 GB (8,511,160,320 bytes)
CFG Loader shows it as 6.1 GB ?? on the screen just prior to launch.
Edit: My cIOS 249 is cIOS249[57]-v19.wad to be exact. Maybe the base of 57 is important.
