Set Wii To Shutdown After Specific Time [Vega]
I always wanted to make a code where you could set a time limit for how long you can play MKWii after you first boot it. Well, here it is.
This code allows the user to set a specific time to force the Wii to shutdown regardless of what you are doing in the game. The shutdown is handled automatically.
NOTE: This code makes use of memory addresses 0x80001640 thru 0x80001643. Make sure no other codes are using those memory addresses.
