It's the weeaboo room. Inside, you find multiple nerds who want to believe they are Japanese that you must murder. It's alright though, because the zombies were going to get inside anyway. Once you do that, a secret passage should open. This leads to a room full of booby traps. Since Jill is a woman, she does not appreciate this room. Once you escape, you find yourself in a room with a N64 Cartridge.
This N64 Cartridge is the secret alpha version of Legend of Zelda: Ocarina of Time. Many fans said that you couldn't get the Triforce in OOT, but if you break open your TV and crawl inside, the cartridge will be inside. After you buy a new TV, also buy a cartridge merging machine. These are rare, but they do exist. All websites of them were replaced with a photorealistic picture of your family as skeletons, though.
Anyway, put a Version 1.00 Ocarina of Time Cartridge in the L slot and the Alpha in the B slot. When the cartridges merge, the Alpha will be gone, but the Version 1.00 Cartridge will be changed into a version of Super The World Ends Wright You: Trials and Twilight Princess. You have to beat Super Mario 64, The World Ends With You, Phoenix Wright: Trials and Tribulations, and The Legend of Zelda: Twilight Princess to get to Ocarina of time. If you do this correctly, your cartridge should transform back to Ocarina of Time. However, if you look at the cartridge it will be 1.99.
To obtain the triforce, you must put Resident Evil 2 in the Cartridge merger in the L slot and Version 1.99 of OOT in the B. The Cartridge you obtain should be really weird, but there must be zombies in OOT for this to work. Kill 3 zombies and then go to the temple of time. If you kill more than 3, you must restart the entire process. Once you go to the temple of time, you will find the triforce waiting for you. Navi shoots link in the face with her newly obtained gun, however.
Wait exactly 49 days and 33 minutes and turn the game back on. It will start off right when you got shot in the face. Navi will be dead, but Link will come back to life. Go to the Triorce, and it will be yours.
