Because there isn't enough lag to do most of the orange clips that are used in runs. For most situations, we have alternatives. However, with Any%, they can be harder than the N64 lag-based equivalent.

For example: You normally use lag to enter Angry Aztec Lobby early, however, you cannot really do this on VC. So on VC, we swim through shores whilst DK is at a certain rotation and damage skew on a beaver. Another example is Factory Early to skip the B-Locker. Both with DK and Lanky, you use Orange assistance on N64 to make it easier. However, on VC, with both, you have to do the orangeless method which is more difficult than with Orange Lag. Most notably when trying to perform DK Factory Early

Definitely, good luck with your project! :)

1. I can't be too sure on what it means as it could be a couple things (So don't 100% take my word on this as it could mean the other thing). However, back when 1-kong started, they used oranges to get into Helm which would mean doing Orange Barrel before you go into Helm. Nowadays, that route doesn't need oranges to get into Helm since we have a way to enter Helm without Oranges, so Orange Barrel is delayed until after Helm.

2. Basically when runners got new controllers and their times started improving purely down to the controller aspect (mainly the analogue stick)

3. A way of unlocking kongs. If you enter Kut Out, you'll start off with Lanky. If you pause exit out of King Kut Out, you'll be in Troff 'n' Scoff with Lanky, even if you haven't unlocked him. If you then enter a Tag Barrel, you have unlocked Lanky without having to shoot the switch in Llama Temple in Aztec. This works with all kongs. All you have to do is keep entering the wrong cannon in Kut Out until it presents you with the kong you want. VIDEO (starts at 1:58) )

4. There's a torch in the Cave in Jungle Japes which can push you out of bounds (Where Diddy's GB and 2 Bonus Barrels for Lanky and Tiny are). The old method was not consistent and involved a kick move to get the push. VIDEO The newer method involves doing an aerial attack backwards into the torch so it pushes you out (and is more consistent) VIDEO |

5. One of the old NLE routes was the FWG route. This involved getting all the guns at the start using a version of ISG known as Funky Weapons Glitch, however, unlike MMM, you didn't get all the moves (Aside from Simian Slam), and you could pause/save/die etc. Since you had to buy the moves for GBs to get, you obviously want to buy the least amount of moves (ie. Don't buy any unneeded moves). One of the later FWG routes was to buy no Lanky Moves from Cranky. You had to collect every Lanky GB that you would collect in the route moveless. Here was the route in case you were interested ( https://docs.google.com/document/d/1yev3xBz-EHVUUsgnX1-YAXta5kBpBT-gklHJ0Dpfj9Y/edit )

6. Double Robot Push is using Robot Push twice in a run. The NLE route was recently modified to cut out some slow GBs early game with a 3-Blueprint turn-in in Factory so that some faster GBs late-game could be added. So Factory was modified so you had to Hatch Skip (Which is an O Clip on N64, but the Robot Push on VC) twice. Once at the start with Lanky to open Tiny's Gate and Grab Lanky's Production Room GB, once after the void-out in Crusher Room to get to Snide's and access the Block Tower area without opening the gate. Hope that helps!

The Various Category leaderboard that Kiwi was talking about (It is in the resources page on Speedrun.com too, amongst other resources): https://docs.google.com/spreadsheets/d/16noULJPEVOA4cA9YOy6zRkhvjHNbHZlUkIJeo2BtV3Y/edit#gid=0

Emulators are banned because they cannot emulate the game properly. It most notably can run faster on Emulator.

Saying that though, it's not too difficult to set up an N64 to run the game :)

Yes - There is a leaderboard for it (It just doesn't automatically show when you head to the SM64 page on speedrun.com)
