Launch Game
Contrary to the title of the selection, "Launch Game" doesn't actually start a Wii backup. Press "A" on this selection to run a diagnostics test on your backup to see if it is in proper working order.
Config Options
Pressing "A" on this selection will take you to a generic options screen. At this point, you can change several options from "No" to "Yes" or vice versa: "Boot Lang," "Force PAL60," "Force NTSC," "Force PAL50," "VIDTV Patch," "Hook Type" and "Ocarina On." The default settings work as they are, but tinkering is allowed.
Rebooter Options
Selecting this option brings you to a standard options screen. The default settings work, but you can switch any "No" to "Yes," and vice versa. The options are as follows: "Recovery Mode," "Region Free," "Remove Copy Flags" and "Button Skip."
About
Pressing "A" on "About" takes you to the credits for the developers behind the Wii Backup Player.
Exit OS
Selecting this option will return you to the Wii Menu.
Press B to Launch Rebooter
If you follow the notice at the bottom of the screen and press the "A" button, the rebooter will launch, allowing you to play your backup Wii game.
