One time a few years ago I was starting Goldeneye64 and was bored on the title sequence, so I started mashing the A button so it would load. After hitting it about 6 times, it loaded. On the main load select screen there was a CHEAT OPTIONS menu at the bottom with ALL CHEATS (invincibility, all guns, unlimited ammo, dk mode, tiny mode, invisible, turbo mode, 2x rocket launchers, 2x lasers, 2x golden gun!, etc.). When I clicked on a file/ level select, it showed all levels unlocked (even the bonus levels for 007 dificulty).
