While you can't get the Triforce, there is a way of seeing it. Thanks to Mew375, we can give you the codes to see the Triforce with a Gameshark.

V1.0 Codes Needed:
Beta Quest - 8011B9E3-0000
Moon Jump (press L to fly) - D01C84B5-0020 811DAA90-40CB

V1.1 Codes Needed:
Beta Quest - 8011BBA3-0000
Moon Jump (press L to fly) - D01C8675-0020 811DAC50-40CB

Here is the process that needs to be followed in order to see the Triforce on V1.0 and V1.1:
Start your game with those Gameshark codes on and watch the N64 logo until it disappears. You'll then appear in Hyrule Field at night in the Beta Quest. Run towards the drawbridge that enters Hyrule Market. Press L to fly up and over the drawbridge and fall down to enter the Goron Shop.
Let the Goron Shop fully come up from the fade before trying to leave otherwise it will mess up and you'll start falling. Now turn Link around and go back towards the entrance stepping slowly and not running to leave.
You'll now be in the Castle Courtyard in the very ending sequence where it would normally flash “The End” and stuff with child Link looking at Zelda. If you have V1.0, you will see the stuff that would come up except the Courtyard will still be in color and you can move. If you have V1.1, you will not see this but just the regular Castle Courtyard.
Now go over to one of the walls and make Link face the very center where the flowers are. Press L to start going up and when you get through the “celine” that you can go through. Now start pulling back on the analog stick to make Link float back. Now let go of L to start falling. Fall until you're below the scenery and start pressing L again and pressing forward on the analog stick. Go forward until you start swimming in the water. Swim forward and try and get right under the middle of the flowers.
Now let go of everything and float to the top and let Link surface. Now after Link surfaces, press Up-C to look around. Look down towards Link's feet and to the left. There is the Triforce!
Here are the codes needs to see the Triforce on V1.2:

Beta Quest - 8011C093-0000
Moon Jump (press L to fly) - D01C8D75-0020 811DB350-40CB
Warp Anywhere - D01C8D75-0010 8111C015-00F0

Here is the process:
Start your game with those Gameshark codes on and watch the N64 logo until it disappears. You'll then appear in Hyrule Field at night in the Beta Quest. Pull out your Ocarina with a C-button and play the Prelude of Light (Up-C, Right-C, Up-C, Right-C, Left-C, Up-C) and when asked if you want to warp to the Temple of Time, say Yes. When the screen starts to fade to white, quickly press R and hold it until you appear in the Castle Courtyard.
Next go over to one of the walls and make Link face the very centre where the flowers are. Press L to start going up and when you get through the “celine” that you can go through. Now start pulling back on the analogue stick to make Link float back. Now let go of L to start falling. Fall until you're below the scenery and start pressing L again and pressing forward on the analogue stick. Go forward until you start swimming in the water. Swim forward and try and get right under the middle of the flowers.
Now let go of everything and float to the top and let Link surface. Now after Link surfaces, press Up-C to look around. Look down towards Link's feet and to the left. There is the Triforce!

heyrðu væni minn, litli rauðhærði hnakkostaógeð,
þú virðist ekki hafa skoðað dæmið í gegn ,fábjáni.

þetta fáránleg spurning hjá þér ljóta drulla. . Heimskt fólk hinsvegar,eins og þú faikus sem taka allt bókstaflega sem þeir hafa heyrt einhverstaðar og eru svo fuckin tregir að manni langar helst að taka augun úr þeim og láta þá éta þau.

það sýnir bara heimsku þína,ég er viss um að það sé allavega eitthvað ofan í rotnaða heilanum þinum..
