How to do a weathertenko in 150cc using the new setup with pause buffer
I highly recommend using the OverKart 64 ROM with the practice mode to learn and practice weathertenko, its super easy to use the savestates so its ideal to work on the skip.
1. Get mushrooms
Pretty obvious. Just go get the item box further up the track, trigger on 5 or 6th place for better chance to get them and go back to the finish line.
2. Position yourself
The position is pretty precise to setup, you need to be on the exact position for the trick to work, otherwise it will fail even tho you got the following steps right.
Once you get mushrooms, go just a little bit further the finish line. Aim for the dark brown line on the mountain to the right just like the image bellow
Get close to the line, align the kart perfectly close to the mountain so the right wheel doesn't clip inside of it.
After that, position your kart just barely over the tiny light brown patch (green rectangle) on the ground just like the image. To help you find it, you can look for the tiny black patch (red circle) right next to the end of the line.
3. Aim at the mountain
After setting up yourself, you just have to turn to face the mountain on the left side of the track. Use Jump to turn instead of A+B turn, otherwise it will ruin your position.
Once you are facing the mountain, aim for that black patch (green circle), it is quite easy to recognize because it's the biggest black patch in that area of the texture and try to get your kart aligned to it
4. Pause buffer and switch input
Now here is hardest part: you have to pause on the frame right before hitting the wall.
Simply press Z to use a mushroom without holding A or any other input. Pause at the right frame and then HOLD straight LEFT and R. Unpause while still holding left and R and if you did everything correctly, weathertenko should be guarantee.
You have to get a feel for it. Overall, Weathertenko with the setup is easy in a way but still hard to execute consistently. It is definitively easier than no setup at all and not recommended for begginers.
