PurpleSun | [TAS] Super Mario Galaxy 2: Rightside Down GS1 in 45.28s @PurpleSunTAS | Uploaded 3 years ago | Updated 9 minutes ago
Luigi fireballs his way to a Green Star in 45.28 seconds [IGT, 2717 frames].
Many of the strats were adapted and altered from nemi's IL run: youtu.be/OK_-u7dJL0Y
UPDATE: Yaasd suggested a backwards bounce at 0:28 that continues down below the lifting platforms, and it's an improvement of 0.5s: youtu.be/3t_9nZJqyJk
For the fall down to the flower, I performed an instant wall release by grabbing the very bottom of the wall, so far down that the game thinks Luigi should slide off it instantly. This lets me keep the same backwards angle but resets falling speed so I can make it straight to the flower. This technique is also used in Honeyhive Cosmic races: youtu.be/tOT9CZDjyzc
Spinning after the backflip might improve the next part as, from what I remember, spinning has slightly faster backwards speed as a backflip, although too much speed would overshoot the double Goomba bouncing which is done for even more speed overall.
P2 is useful for holding the Paragoomba in place to bounce off it without having to spin.
The moving platform is really awkward because of the small gaps to fall through - holding neutral will automatically grab a ledge (but I don't remember testing up or down, believing it would have the same result because 2D)
So I decided to fall and hold left to wallslide off the platform and be turned around at the bottom. This meant I could fall backwards to the Thwomp section, using the other moving platform as a ceiling that stopped a spin going so high and landing later.
To get to the Fire Flower, I found a quick spin after a walljump on the left was slightly faster than walljumping from the right.
The fireball section itself could use some improvement; looking back at some of the movement, it's very clunky.
However, I am satisfied with what happened between 0:44 and 0:47, with a sideflip and fireball angle change that interacted with the falling crate in such a way that Luigi grabbed and instantly climbed the ledge on the right. This allowed for a quick backflip to the gravity flip, although this might not be the best strat as it meant I had to throw two fireballs at the next pile of crates instead of just one, due to the lack of forward momentum with the fireball angle change that wasn't enough to long jump and escape the falling crates.
Finally, I triple jump off a crate and walljump off-screen, holding neutral as soon as Luigi jumps to bypass the restricted walljump speed (a trick known as neutral walljump strain), so I could get more forward speed by holding right, enough to be able to triple fireball into the star.
This strat saved 8 frames over the normal strat of entering 3D and long jumping back in. You might not be able to see what's going on but sometimes a little mystery is nice in a TAS.

Luigi coasts to a Green Star in 22.95 seconds [1377 frames, IGT].
The backflip at the start saved 0.15s over long jumping and spinning.
Jumping over the railings ended up being a little bit faster, and jumping further along the rolling rail is also faster as it gets to the high-speed point earlier.
Down the slide, swinging between the sides ended up being ~0.2s faster than taking a more central route.
There isnt much to say about the last stretch other than a light left turn around the Galoomba to avoid slipping down, and then light right turning towards the star.

Green Stars TAS WIP
Started off by showing the pre-galaxy stuff, including going fast enough to the helm to beat the 2P textbox by 6 frames. Unfortunately you cant cancel the textbox by pressing the helm button at the same time.
GS1 - 7.28 IGT - 1:13.90 real-time split
With Japanese text and without the 2P textbox, this would be 5.93 (textbox loses 0.75s, English loses 0.6s).
Its faster to take this star with cutscenes than GS2, as skipping cutscenes for GS2 gives a better cycle on the moving platforms.
Taking the roof route was only 7 frames faster than going around.
The low long jump only saves 1 frame over a fruit bounce.
GS2 - 19.61 IGT - 2:17.10 real-time split (1:03.20 segment)
The IGT is slower than my IL TAS because, in the IL, the first cutscene skip is delayed to perfect the cycles for in-game time; this doesnt matter for real-time.
To be faster in real-time, the platforms are further manipulated by having slightly suboptimal lines (and a swerve) at the start of the 2nd planet to keep the platforms on camera so they keep moving along the cycle, the main platform rising up ~20f earlier than with optimal movement.
Delaying the first cutscene enough to make use of the first yellow platform (skipped with a spin here) is barely not enough to make this earlier real-time cycle, even with more optimal lines.
GS3 - 36.08 IGT - 3:48.63 real-time split (1:31.53 segment)
Backflip over the hill was 0.4s faster than long jumping around the side.
The camera is turned just before the launch star appears in order to minimise its movement during the mini-cutscene, which saved 2 frames.
Originally on the glass planet, I landed on the checkpoint, backflipped up, and long jumped through and over the Octoomba to get the same long jump from 1st to 3rd platform. But the cycle wasnt great and I lost speed on the 3rd platform.
So this other route (which had been thought up a couple years ago) that seemed slower at the start ended up being faster by 0.41s, as it kept running speed after the long jump from platform to platform.
Also, while Im using a pre-made 9999 coins file by bloodtv_ that means collecting coins doesnt matter, I decided to grab the coin with P2 just because.

Luigi nabs the fastest Green Star in 3.06 seconds [IGT, 184 frames].
This is a 1f improvement over the previous 3.08 by myself in 2019: https://youtu.be/b-yFYZLkmps
The frame save is embarrassingly simple. By keeping enough speed while straining the second long jump further to the right (and left once the camera has turned), Luigi hits a higher point of the stars hitbox.
I had tried various lines in my previous TAS but none had improved; the difference was not losing too much speed so it doesnt drop in front of the star before hitting the top spot. Its all spheres. Tears for Spheres.
The low long jump is caused by long jumping off a ledge where the tilt hasnt been calculated properly, reducing the yspd (9 units initial speed, versus the normal 15). Unsure if its to do with edges in general, or specifically a slanted edge.
This strat saves 1 frame over the fruit bounce strat.
Could there be more frames to save? Yeah, I think so. Theres a way to get an even lower long jump, although its horizontal speed is low too, so a following long jump hasnt been able to get over the edge without a wayward line. Currently sits at 3.13s despite a 4f earlier 2nd long jump.

![[TAS] SMG2: Sky Station GS3 1xA full game route](https://i.ytimg.com/vi/Ey9akCDygYo/hqdefault.jpg "[TAS] SMG2: Sky Station GS3 1xA full game route
The A press is used to start the Lumas cutscene, and is done in such a way to instantly end the cutscene, resulting in an unnecessary jump from a necessary A press.
At the start, I used Mooshs strat from his run of 0x gameplay A presses (i.e. excluding dialogue): https://youtu.be/-zCuJPmgL_A
The only difference is the angle and trajectory of the triple bounce, as Moosh had a better angle that bounced off the rock and landed closer to the Chomp, whereas I found that my angle could bounce off a green bulb that a Chomp pushed out. Probably slower but I like the variety.
In theory, the textbox skip works because you stand on the edge of the Lumas trigger area, and then get pushed off without touching the joystick (in this case crouching and uncrouching with Z) and press A just before leaving the trigger area. This A press starts the dialogue cutscene (evident by the camera zoom), but as Mario then leaves the area, it counts as ending the cutscene. In this case, ending the cutscene triggers the Luma to transform into a launch star.
There are other NPCs such as the Gold and Silver Gearmos from the Cmere levels where you can do this technique, but nothing happens aside from the camera zoom. The theory there is that because the progression from talking to the Gearmo (spawning the cage) happens *during* the cutscene, instantly ending the cutscene skips that and so it has no result.
As for the final planet, while landing on the higher platform before the Octoomba reaches the Octoomba 20 frames earlier than the lower platform - and also is fast enough to backwards bounce past the first elevator - it ends up getting a slower cycle on the third elevator, ultimately being 0.3s (24f) slower.
Taking the low route, its necessary to get an electric shock in mid-air to get up to the Octoomba, as spinning from the ledge is barely too short and I couldnt manage to get a ledgegrab.
The second electric shock wasnt necessary as I could have just gone down at the second elevator and spun across, but I did it because of the accidental bouncy slide across the second elevator.
On the final elevator, I turned around and got clipped into the ceiling before getting pushed out with a walking animation, and finally a spin to the star.

Luigi and P2 jump out of water like those fish that jump out of water to collect a Green Star in 1 minute 21.61 seconds [IGT, 4897 frames].
The improvement here was suggested by Really_Tall, going around the water circle in the final section instead of swimming through it.
A regular water jump barely cant make it to the water above (going to where the 1-up is) and water long jumping further right takes too long overall.
But jumping back onto the solid part of the circle and backflipping up gets to the Goombas platform very quickly, and a backflip from there reaches the trigger for the water blocks as early as possible, earlier than bouncing off the Goomba or water jumping from above.
This saved 1.33s over the previous run, and saves ~2.3s over the normal RTA method of going through the circle and backflipping off the top of the Goombas platform.
The water here is strange - aside from the bottom part, entering with a jump or spin will not interact with the water until you have reached the peak of the jump/spin, so you can travel quite far into it. A jump + a spin before the peak goes even further.
[from previous run]
The first area could use some improvement. At a certain point, single skate jumps and double skate jumps have more speed than a skate long jump (ljs have an average speed of ~26 units per frame, jumps have ~27 units per frame over a shorter distance). Not sure at what point this extra speed occurs as trying skate jumps from the beginning had nowhere near that speed, and even after one lj, a single jump didnt get that speed.
The second area is where P2 shines. Breaking the bricks as P2 saves 0.3s over ground pounding, bursting the bubble saves 0.4s over trying to avoid it, breaking the box and shrinking the spiny at the start of the underwater section saved a few frames from a better line and no break stutter (Luigi stops when breaking a box underwater), and hitting the lever saves 2.5s.
This is where the first water long jump is; by holding Z when entering water and then picking up enough speed at the surface, you can long jump out of water.
Long jumping early and following with a single jump onto the used block saved 0.5s over long jumping later straight onto the used block.
The final section gets interesting. The moving water blocks at the top only start moving once you pass a point somewhere just above the big blue arrow, so optimisation is only really required in the first half - the second half doesnt have to be perfect as long as you make the cycle to get the earliest possible long jump to the star (when the third block is slightly raised).
[old ideas removed, see here: https://youtu.be/6-UTeD07tqI ]
The rest of the section was simple, as noted above, and involved setting up another Z-held water entry to get two water long jumps, one to the second block, and the final one to the star.
A weak spin was the only way to grab the star from that early of a long jump, so it saved a couple of frames.

Luigi floats away to let a Hungry Luma starve in 0 A presses.
This is tool-assisted.
This is a gameplay improvement of 0.5xA presses, not needing to hold A for higher spins or bounces at any point.
The main improvement is cutting out 6 A presses of dialogue (menuing) from the Hungry Luma.
After getting the new GE2 skip with just a sideflip setup for the crystal float (https://youtu.be/90QX5QEvo-s), I decided to try with just a Goomba bounce. As Mario, this is much harder and hasnt been done yet, but Luigi is much easier to get floating, and in this case, the flipping animation that usually happens on a crystal decided not to for reasons.
UPDATE (just a few hours later): Mario can do it at least 0.5xA https://youtu.be/XBWQlODVYKg
The star grab hadnt been proven without holding A (0.5) but was considered most likely possible and here it is.

Luigi launches off a Romp to collect a Green Star in 1 minute 14.10 seconds [IGT, 4446 frames].
So this isnt exactly optimised but I had to show off this crazy new strat that happened completely accidentally. UPDATE: Romp launch has been optimised some more but still needs work: https://youtu.be/xsd_7sIqS90
Firstly, I mostly followed nemis IL (https://youtu.be/Wy2RYwIa-Ck?t=139) throughout the level, improving the first planet with some tighter long jumps and an earlier upwards strain towards the launch star.
I also used P2 to freeze a couple of troublesome fireballs.
For the second planet, I long jumped from the edges at 0:37 and 0:42, as edges of moving/scrolling floors do not have any friction, so long jumps are normal instead of being pulled back slightly.
This could save time for other long jumps here but the long jump route played out perfectly to bounce off one of the Pokey heads onto the block.
I tried long jumping earlier off the block to get horizontal displacement momentum (which happens sometimes when long jumping off a moving platform) with a forward angle, but this only went sideways, and walljumping off the closest wall is slower than angling to the right and jumping off the left wall.
For the slide, I started out doing the known strat of getting the Romp to push Luigi by sliding up against the edge, which wont get him crushed.
Whenever Luigi would start getting pushed to the side or start clipping into the floor, I tried jumping at different times with different angles and time spent holding A in order to stay in front of the Romp but above ground.
One time, though, this ended up with jumping at a certain point where Luigi had clipped slightly inside the Romp and floor, so the game had ejected him by ~170 units. The jump then conserved most of this speed, going at a hspd of ~130 units/frame.
Assuming units are centimetres, this would be at least 174 miles per hour. This speed was constant as speed cant be changed during a slope jump in SMG2.
Angle also cant be changed from slope jumps, so I had to deal with going to the left. I timed a ground pound to land up-left of the star, so I could move down and right at a faster slide speed to reach the star.
This strat was 3 seconds faster than getting Romp pushed all the way.
This could obviously be improved by just getting the launch earlier, but could also be improved if we can figure out how to jump to the right, which may simply be a case of getting pushed on the left edge of a Romp so that we have to angle to the right to keep getting pushed.

Star order would matter with the fireball cycles for GS1 if it werent for the 2P freeze strat levelling out cutscenes and no-cutscenes. Otherwise GS2 first would be 3 or 4 frames faster.
Green Star 2 - 19.86s IGT - 1:31:06.06 real-time split (1:16.11 segment)
This is a 0.69s improvement over my 2020 TAS (0.69s plus cutscene difference): https://youtu.be/5PdldVGADec
One of the key improvements was being able to long jump into the sideways lava wall without having to spin cancel, which saves 9 frames. Usually, getting a lava-wall boost here would send Luigi downwards (As seen here by nemi43: https://youtu.be/EWGiL2oEMRg?&t=218) but there is a precise spot in the corner that sends the boost sideways.
The brief 180 in the boost sequence helps to line up the third boost to get an earlier gravity switch that can stay close enough to the left to be able to get the extra boost, while also managing to go further up the new gravity field to end up closer to the star. This saves 18 frames over trying to go straight right the whole time.
The other key improvement is in the final boost, where it is 21 frames faster to go around the Whomp rather than under it, which was only possible with the earlier gravity switch.
A couple of frames were saved by going neutral before double jumping which affects jump height and speed, and another frame was saved by holding back for a frame during the double jump to have a lower speed triple jump, keeping it closer to the star.
Green Star 1 - 11.33 IGT - 1:32:00.48 real-time split (54.42s segment)
This is a 0.7s improvement over my TAS made in 2020: https://youtu.be/y-k1jR0HPbs
The IL WR by Ethanrocks (https://youtu.be/m759Lysh9IU) showed that a single jump was enough height for a fireball boost to reach the crate, which made up the bulk of improvement over my TAS.
The issue with this boost is that it wont let you long jump until the end of the fire run, but this run can be cut short by going onto an edge.
Some slowing down of the long jump around the curve resulted in a better long jump off the step that overall saved 2 frames.

Luigi yeets into a Green Star in 33.73 seconds [IGT, 2024 frames].
I wait the fly-in cutscene until the last possible frame to skip it, simply to start the in-game timer as late as possible into the chomp cycle. Waiting the first cutscene for a brief moment might save a few frames. Oops. P2 helped save that in-game time by being able to hit the lever much faster.
A little bit of time for a playaround while waiting for the Chomp, making sure not to spin the Octogoombas to cause hitlag.
Being on the ground in front of the Chomp when it explodes saves 0.5s over the long jump strat that is done in runs. After the launch star cutscene, the camera moves to centre Luigi, and so the long jump makes the camera tilt upwards, but staying on the floor skips this tilt, gaining control much earlier.
This strat had been found by jda7 long ago.
However, the reason why runners do a long jump is because it has some kind of effect on Luigi that lets him start moving much earlier on the 2nd planet. But we found out that backflipping can also get this effect, so I backflip on the frame just before losing control to be low enough for the cutscene camera skip but still get the early movement.
The next planet was relatively simple, the bounce on the Gearmo being slightly faster and also setting up a perfect long jump chain.
Camera cancel doesnt appear to work on the 3rd planet, but jump land cancel does.
Finally, I got a good angle on the flip panel jump by turning while spinning off the edge, and then turning more on the panel, so I didnt have to go off to the left for a line-up.
