I guess you could call this a cheat, but it's more like a glitch for Tomb Raider 3. You use it to get all the weapons and medi-packs in Lara's Home. Here's what you do:
Go into a new game, and do the gun cheat. Then level skip a few levels, and without turning off the playstation, quit the game and go into the training level. Lara should have 2 heads, and when you go into her inventory, she had many flares, along with medipacks, save crystals, and all her guns.
