Cheats for Resident Evil 3 (GAMECUBE)
Barry Burton ending:
The only way to see Barry is if ending B is unlocked. To get this ending, jump off the bridge when fighting Nemesis Type B. After the jump off decision, the final area of the game will take a somewhat different path. You will have to fight off Nicholai in a chopper. It is recommended that you bring a Magnum and Grenade Launcher (or Rocket Launcher if it has been found). You can also choose to negotiate with him.
Barry Burton ending 2:
Jump off the bridge. Play until you reach the room with the Radar Tracker. Take it, and try to leave the room using the door you entered. Nicholai will call you. After killing him, Carlos will enter. After talking with him, leave the room (do not use the hatch to the Rail Cannon). Turn around and get in the radar device room again. Carlos and Jill will listen to a radio call from Barry and the game will continue with the final scenes.
Mercenary mode:
Successfully complete the game one time to unlock mercenary mode and save the "Next Game" file. Start a new game, choose that saved game, then select mercenary mode. This mode involves controlling Carlos, Mikhal, or Nikoli from the train to the starting room with a two minute timer. Killing the various opponents and rescuing civilians during the journey will add more time to the clock. A rank and money will be awarded after the game is completed. The money can be used to purchase better weapons for the next mercenary mode game.
Alternate costumes:
Successfully complete the game under the easy and difficulty settings with any rank better than F to unlock new costumes for Jill in the Boutique.
Epilogues:
Successfully complete the game under the hard difficulty setting to unlock Epilogues. Epilogues are a short diary description of each character in the entire Resident Evil series which describes what happened with that specific person after their adventure. Getting better ratings can unlock the other epilogues. There are eight total Epilogues that can be unlocked.
Operation Mad Jackal option:
Successfully complete the game under any difficult setting.
Jill's diary:
To get Jill's Diary (a file), collect all thirty files in the game in order. Then the first file (Instructions Manual, blue) will become Jill's Diary.
Enhanced Weapons/Ammo:
You can only create enhanced ammo while playing under the hard difficulty setting. When creating ammo with the reloading tool, save enough gunpowder to mix up the same type of ammo eight times. On the eighth time, the game will prompt "Do you want to create the enhanced ammo?". Select "Yes". This ammo is more powerful, may have slightly different effects, and once loaded into a weapon will change it into an "enhanced weapon". You can only create two types of enhanced ammo: 9mm handgun bullets and shot gun shells. The only different effects the new bullets have is that they are far more powerful.
