Having caught up on this, you had a great informative commentary style Weatherton. It made me think you should consider doing a commentary track for the final product.
Oh, and the Mushroom Cup run wasn't bad either!
That Mushroom Cup was worth the wait. Way to go, Weatherton! Here's hoping the other cups won't be as hard to make (since the routes are already figured out for those).
Patashu, thanks for posting. I was just going to do the same :) A lot of fun and excitement over at mariokart64.com this week!
Here's the full background:
On 2-Feb, Greg Ihnatenko mentioned a previously unknown effect of building up speed while not moving. I involves getting stuck in a wall for a few frames and we're calling this the Tenko boost. I replied "Greg, now THAT is worth testing with TAS". What he was describing (about using this boost to make a new type of jump on Choco Mountain) sounded very plausible.
Later that same day, Greg created a topic titled New Shortcut!. He had cleared the wall on Choco Mountain and landed on the track down below while making progress on the lap. This was the first new shortcut in time trials in the last decade. Very big news. As soon as I saw his video I said "Greg, I want to go on record as saying I think this could result in a sub 10 second lap." Watching his video had given me an idea for a lap skip using the Tenko boost but differently.
On 3-Feb, I had been trying my lap skip for about three hours with TAS with a lot of gut-wrenchingly close results but no success yet. I decided to do a full TAS of the Tenko boost shortcut that Greg had demonstrated combined with another wall jump used in the current WR. The result was approximately the time that Myles Bukrim had predicted (15"5X).

Though I used a couple newer techniques at the end of the lap that no one is doing in realtime speedruns.
Six hours later, I managed to successfully trigger a lap skip for a time of 6"17 and posted as such in the Mario Kart 64 message board (As well as Mark Jone's twitch channel http://twitch.tv/dntn31). This was yet another new shortcut, different from what Greg had found but using his Tenko boost. I called it the "Weathertenko skip". In Mario Kart, new strategies are generally named after their discoverer.

An hour later, I optimized my original hit for a 4"91.

Yesterday, I streamed a walkthrough of what I was doing to trigger the lap, frame by frame at http://www.twitch.tv/weatherton and also experimented with some changes. I plan to continue streaming my TASing from time to time as reception was good and people wanted to see more.
I am in the process of switching to BizHawk and need to find some memory addresses. I would appreciate any help anyone could give me. I also have some relevant GameShark codes that should help:
1. Velocity
Relevant codes:
Minimum Speed Modifier (Player 1):
810F6A10 45??
Maximum Speed Modifier (Player 1):
810F6BA4 ????
810F6BA6 0000
Speed Values:
439B Time Trials
4391 50CC
43A0 150CC
43F0 >100Km/h
43C0 100Km/h
4360 40 Km/h
4310 20 Km/h
2. Item
(This should tell me what item I would get if I hit Z on the current frame)

Weapon Modifier (Player 1):
80165F5D 00??
80165F8A 00??
Unlmited weapons of specific type:

If you have the values in mupen then try this.
1. Convert the movie for BizHawk.
2. Check skip lag frames in BizHawk.
3. Play the movie in both but have it paused so both are on frame 0.
4. Choose an address to find.
5. Check the value of the address in mupen.
6. Search for that value in BizHawk.
7. Advance to next frame.
8. Repeat steps 5-7 until you have found the address.
If I don't understand your question correctly than ignore this.
Projects:
Interested in TASing N64 Mario Golf.
GBA Mario Tennis: Power Tour is on hold.
Great suggestion! I will give this a shot for finding the speed / position values I already had in Mupen. As for the item values, the only thing I have are the GameShark codes. It seems these should be readily transferable to BizHawk, but I don't know how. Anyone know?
I'm so hyped for this TAS, especially since I started to run this category a few months ago. Your previous work on this game was one of the reasons for me to start doing it :)
Current project: Gex 3 any%
Paused: Gex 64 any%
There are no N64 emulators. Just SM64 emulators with hacky support for all the other games.
I plan to live stream some of the process at http://www.twitch.tv/Weatherton so follow me if you're interested :-) I will plan to update progress in this thread too.
