To lock the style so that it doesn't change with the d-pad, use the
gui_lock=1 option.
Now, that just stops you changing the gui mode, but if you don't want to be able to change to the console-based list view, then also disable the action of the B button and the - button. You can do that with
button_-=nothing and
button_B=boot_game or some alternate actions according to those options. The suggested ones will make it so that B also launches games and the - button does absolutely nothing. You might also want to use the "random" action for either button that will get Cfg to randomly select a game from all the installed games.
For childproofing, it is also recommended that you use
simple=1. That means the kids can't install, delete, format the partition or change options for the game and it also disables the start confirmation screen (so they push A to start the game instead of twice). You could set these options manually via
disable_install, disable_remove, disable_format, disable_options and confirm_start, but
simple controls them all at once.
It should be noted that although you disabled installation of games, you can still do that via password. By holding the 1 button, a prompt will come up to enter a password. You can change that password, but the default option is
unlock_password=BUDAH12 which corresponds to B, Up, Down, A, Home, 1, 2 on the Wiimote. You can set that option to any other combination of up to 10 buttons.
Unlocking the admin lock also allows you to access the "Hide Game" option on the options menu. Hidden games will only be displayed after the password has been entered, meaning you can lock out the games that you don't want your kids playing but can still play them yourself.
For other option information, make sure to check my
Configurable Options guide and the Configurator, which has plenty of info on each option both via tooltips and via a help file.
