Wii freezes when changing Widescreen settings from 16:9 to 4:3 and then back again.
I have a problem that you guys have probably never seen before. I've tried many things to fix it, including mauifrog's guide to fix a semi-brick but I still have no luck in fixing it.
I can enter the Wii settings menu fine, but after changing the widescreen settings from 16:9 to 4:3 and then back to 16:9, the Wii freezes up (black screen, high pitched continuous sound coming from TV).
I've got a launch model PAL Wii on 4.2e, bootmii installed, no system menu hacks, plenty of free blocks, this never used to happen - has only been happening in the last few months, have a genuine WiiKey v1 installed (from before HBC existed).
Any ideas why this happens or, more importantly, how to fix it?
