http://www.gamefaqs.com/snes/588387-indiana-jones-greatest-adventures/cheats go here for any passwords you may need, but I suggest using level select passwords and game over passwords to practice

Game Over Right, Left, Right, Left, Up, Down, Y, A Level Select L, R, Down, Up, Y, X, Select

you press start during game play, during pause input buttons briskly...doesn't have to be incredibly fast. level select first, un pause, pause again input game over...you can now access any level through the options, then regularly starting a game.
