Lately I've been tinkering with my Nintendo Wii (you may have heard of it). In order to play newer stuff it is necessary to update some cIOS.
Otherwise, at the very least you'll get a black screen, or if the game loads it may not be fully functional. I had this issue where Rodea the Sky Soldier would reboot all the way back to the system menu when I tried to change the in game language. And the voice would remain in english (bleajh).
At the very least cIOS 249 and 250 need to be updated with the d2x cIOS. Use the beta 53 if you want better usb support, use the beta 52 if you want better emunand support. This is how I allocated the cIOS:
cios 247 base 37
cios 248 base 38
cios 249 base 56
cios 250 base 57
cios 251 base 58
Regarding cIOS 236, it seems it is no longer needed, still it doesn't hurt to (re)install it. Just make sure you use the "mod" or "pro pirate" version of the installer. If you use the regular one make sure to press "2" especially if your dvd drive is hosed.
Other things I did were update the homebrew channel from 1.1.0 to 1.1.2, install Boomii as IOS (no vulnerable "boot1"), install Priiloader and update USB Loader GX (especially for its superb Nintendont integration).
Selecting the cIOS 250 Rodea now allowed me to change the language, and other black screen games now load.
All in all, the Wii is a great machine and homebrew development still seems to be going strong. It is my go to emulation machine for pretty much everything (but arcade). Component video is a delight on a CRT, almost as good as RGB.
Well, that's it for now.
