Option #3 Recovery Menu via savemii or savemiifrii
If you have a black screen, you may be able to start the wii's recovery menu by using savemii or savemiifrii. If the recovery menu loads, it may be possible to execute applications using autoboot disks, with a preconfigured autobooting modchip.
If you buy a modchip, make sure it is preconfigured by the seller to autoboot and region free, without any update blocks enabled.
To try savemiifrii, you will need a gc-controller in port #4. Orginal controllers from nintendo require modification of the dpad for this to work. For this reason, cheap generic controllers are usually better. Hold all four directions of the dpad down at the same time. Continue to hold them down and boot the wii while holding. If it works you will see a blackscreen with you system menu displayed in the lower right corner.
