So I know to actually attempt this it would involve a modchip and system menu 3.2 or older for the bug truncha bug but listen me out please.
Say I have a disc I made that the banner is bad so when the menu goes to load it being accident prone as it is once the disc channel actually loads the disc the system menu in theory would freeze and you would be stuck. Could you reboot the system and eject the disc before it loads again? Just curious on how the Wii handles the more out there type of things like that and what would need to be built in a custom menu to protect from bricking issues.
