Unused Main Menu SGB Border Set Routine
00A-45D-E62

Unused Main Menu SGB Border Set RoutineNormally, when the game detects that a different border other than the default is loaded, it will load the default when an in-game reset is initiated. There is an additional border check routine that is unused because it is only possible to set the border before the menu selection. Game Genie code 00A-45D-E62 will set the first border allowing the menu border check routine to be active which will now load the default border.
