This glitch removes the "PREV" symbol so you can use a specific employee
an unlimited number of times to do a certain job of game making (scenario,
graphics, sound). When you are going to make a game and you are prompted 
to pick an employee to pick a scenario, press "back" on the bottom right.
Now tap "ok" again on the "Game Direction" window and you'll be prompted 
to pick the employee again. You'll notice that no employee has the PREV 
symbol anymore.
