These are the pure Hex Codes for Resident Evil. To hack Resident Evil you must open your savedat1.dat file in your saves directory. Find line 00000320 and search for all the 0000 and then add these for your cheats:
Start the game as Jill save the game in the first slot and edit it with your favorite hex editor. Move at offset 032C in the file (the first slot free after you get the 3 ink ribbons) and enter two bytes: 38 01. This gives you the closet key. Exit and reload the saved game. Go straight in the closet (from the main room of the mansion take the narrow door on the right wing, enter the room with the mirror, then proceed in the corridor, open the door and enter the room with the large mirror: right to the mirrors there's a door; now you can open it with this key). Go to the right end of the room and search for the suits. Jill will change her outfit! Now she's really gorgeous! Have fun.

Kill the snake and not be poisoned
When you get to the guy poisoned by the snake he will ask you to get him the antidote. You go get the antidote, you take it and you leave it in the chest. You go and look for other clues and after a while you go to the poisoned guy and you find him dead. You take the key. You take from the chest munitions & weapons, some green plants and the antidote. You kill the snake and after you go out of the room you use the antidote.
Kill Chris when you have control of Rebecca
After the snake poisons Chris you get out of the room and get control of Rebecca. You go whit Rebecca and don't get Chris the antidote (walk around the house) and after a while return to Chris.
