K64:100% Manip Route

This article is a guide on how to perform the RNG manipulation for the 100% speedrun of Kirby 64: The Crystal Shards. For a general explanation on how RNG works in this game, click here

How to use this guide

In order to use RNG manipulation in a run, the instructions in the next section must be followed first, and then the manip must be carried throughout each level, with instructions on how to do so presented below. Kirby 64 takes so long to reset that it would typically not be worth it to try and recover the manip once it is lost, so the run must either be carried forward without the manip or restarted from the beginning. Because of this, it is recommended that runners who wish to learn manip do so sequentially, starting at 1-1, as trying to reset in the middle of a run to achieve a specific RNG value will most likely be slower than dealing with bosses' random actions. Unfortunately, since most of the timeloss due to random actions typically comes from bosses in the later worlds, runners have to learn and perform the majority of the manip before the largest timesaves can be taken advantage of.

The instructions for each level will start with a relatively consistent method to obtain the correct RNG value and copy ability starting from a reset; that way, runners can practice each level on console with the same RNG as during a run. Any time Kirby should advance RNG will be noted, as well as any noteworthy interactions with random enemies. For any sections of a level that do not have explicit instructions, the runner should use normal speedrun strategies and not go out of the way to interact with or avoid enemies. Each section will end with a picture of the picnic or picnics that should appear if the level was ended on the correct RNG value (in some cases multiple RNG values will result in the same value after the picnic is spawned, even though the picnics themselves will be different). The enemy info card from the picnic should not be collected unless specifically instructed to do so.

Before the run starts

Reset the game and mash A through the opening screens to get to the file select screen as quickly as possible. It is recommended to keep a completed file in order to set up the manip before each run. Select any file and choose the mini-games option. Choose any mini-game on any difficulty and pick a character, paying attention to the characters the COM chooses. If the COMs are any of the three following combinations (listed from left to right - order matters), follow the given instructions:

1. King Dedede, Kirby, Kirby: Either connect a second controller and choose two characters at once so that there are two COMs, then start the run, or enter and immediately exit [Boss Battles] twice, then start the run.
2. Kirby, Kirby, Waddle Dee: Either connect a second and third controller and choose three characters at once so that there is one COM, or enter and immediately exit [Boss Battles] once, then start the run.
3. Kirby, Waddle Dee, Kirby: Start the run.

If none of the above combinations appear, press B to exit out and choose another character. If no above combination appears after 3 iterations, the opening screens were not skipped quickly enough and the process must be restarted from the beginning. Once the run is set up, be sure not to play the wrong file or exit back to the title screen; otherwise, the game will have to be reset and the run will need to be set up again.

World 1

1-1

To practice the manip starting at this stage, follow the instructions in the previous section

After the [N-Z miniboss], jump high enough to not disturb the first [Flutter] while using single fire. Throw the ability star to advance RNG once when combining for fireworks, but avoid standing still and advancing RNG a second time. Run along the ground after collecting the final crystal shard in order to disturb the last [Flutter] as soon as possible, then jump over the [Poppy Bros. Jr.] and do not slide into the loading zone. Avoid advancing RNG during or after the [Waddle Doo] fight, putting the ability star into Kirby's mouth and spitting it out rather than throwing it to finish the fight.

1-2

To practice the manip starting at this stage, reset the game and don't press anything until the opening cutscene plays. Skip the cutscene and mash A to skip the title screen, then go to 'Options,' 'Mini-Games,' and play single-player 100-Yard Hop. Immediately pause and choose 'Play Again' 7 times, then quit as long as the puddle is on the third space. If not, reset and try again. Choose a file with 1-2 unlocked, then enter and immediately exit the stage once. After this the RNG value will be correct and 1-2 can be practiced.

Run through the first two dandelions to destroy them and grab single fire as quickly as possible. If too slow, the dandelion will advance RNG one extra time. Only drop near the ground when close to the [Sparky] at the end of the room and destroy it while it's in the air. the [Sparky] should be jumping straight up when destroyed; if it's jumping towards Kirby, RNG will be one value too far and the player must advance RNG one fewer time during the Adeleine fight. Climb the tree quickly, not advancing RNG and killing the last [Sparky].

Advance RNG 12 times during the first phase of Adeleine (11 if RNG was one too far). It's recommended to duck 8 times before destroying the first enemy, then stand still once after each enemy. Immediately stand behind where [Ice Dragon] will spawn. Kirby should start an idle animation before [Ice Dragon] becomes vulnerable. Stand still after hitting [Ice Dragon] once to advance RNG, then hold left during the second hit so that Kirby doesn't stand still. Finish off [Ice Dragon] in midair. Advance RNG 4 times before [Dark Matter] spawns, then advance RNG one more time after defeating it. Stand still to advance RNG one final time before grabbing the crystal shard.

1-3

To practice the manip starting at this stage, reset the game and don't press anything until the opening cutscene plays. Skip the cutscene and mash A to skip the title screen, then play single-player 100-Yard Hop. Immediately pause and choose 'Play Again' 17 times, then 'Play Another Game.' Select 100-Yard Hop again and keep choosing your character and then pressing B to exit and choosing another character until the COMs are Kirby, King Dedede, Waddle Dee, in that order. If that combination doesn't appear within a few iterations, reset and start from the beginning. Once that combination appears, choose a file with 1-3 unlocked, go to 1-1, obtain single fire, and advance RNG twice, then exit the level. At this point the RNG value will be correct and 1-3 can be practiced.

During this stage, only advance RNG by throwing away single fire to grab cutter and throwing single fire to combine for double fire. Don't advance RNG during Dedede's first phase and land the third hit as Dedede jumps to do his hammer attack, then advance RNG once. Finish off Dedede as quickly as possible and don't advance RNG any further.

Whispy Woods

To practice the manip starting at this boss, reset the game and go to the title screen, then wait until the first demo starts playing. Immediately press A to skip it and mash A through the title screen to get to file select. Play single-player 100-Yard Hop, but if the COMs are Waddle Dee, Adeleine, and Waddle Dee, in that order, press B and choose a character again, then enter the game. Immediately pause and choose 'Play Again' 4 times, then 'Play Another Game.' Select 100-Yard Hop again and keep choosing your character, then pressing B to exit and choosing another character until the COMs are Kirby, King Dedede, Adeleine, in that order. If the combination doesn't appear within a couple iterations, reset and start from the beginning. Once that combination appears, choose a file with Whispy unlocked, go to 1-1, obtain double fire, then exit the level. At this point the RNG value will be correct and Whispy can be practiced.

Jump over the Whispy Jr. to the left, then use double fire to the left, damaging the Whispy Jr. to the right and left of Kirby. Turn around and double fire to the right, hitting the same two Whispy Jr.s, then hit the third one twice. RNG should not be advanced by Kirby at any point during the fight. Whispy should give perfect RNG and must be 2-cycled to end with the correct RNG value.

World 2

2-1

To practice the manip starting at this stage, reset the game and go to the title screen, then wait until the first demo starts playing. Immediately press A to skip it and mash A through the title screen to get to file select.

Immediately pause and choose 'Play Again' 6 times, then 'Play Another Game.' Select 100-Yard Hop again and keep choosing your character, then pressing B to exit and choosing another character until the COMs are Waddle Dee, Kirby, Kirby, in that order. If the combination doesn't appear within a couple iterations, reset and start from the beginning. Once that combination appears, choose a file with 2-1 unlocked, go to 1-1 or 2-1, obtain double fire, then advance RNG twice and exit the level. At this point the RNG value will be correct and 2-1 can be practiced.

Throw away double fire when grabbing stone. In the room filling with sand, advance RNG 13 times, then stand still to advance RNG one more time before transforming into stone until Bandana Dee arrives. Put stone into Kirby's mouth and hit the Sparky with it after it hits the ground. After grabbing the last crystal shard, jump over the Sparky and leave it alive.

2-2

To practice the manip starting at this stage, reset the game and go to the title screen, then wait until the first demo starts playing.

If the combination doesn't appear within a couple iterations, reset and start from the beginning. Once that combination appears, choose a file with 2-2 unlocked, go to 2-2, then walk towards the Sparky and inhale it as early as possible without running. Combine it with the [Hack] by spitting it out - not throwing it - and swallow the ability star, then exit the level. At this point the RNG value will be correct and 2-2 can be practiced.

Jump over the first Sparky and leave it alive, then throw away stone + spark while waiting for the first pillar to fall. The next Sparky should do a big jump towards Kirby; slide off the pillar and puff to destroy it. Obtain single fire. In the last room before Dedede, use fire along the ground and eliminate both Sparkys ASAP. Throw away single fire before the Propeller starts moving towards Kirby, then eat it to get ice and don't advance RNG any more.

2-3

Choose a file with 5-1 unlocked, go to 5-1, and inhale the Frigis after it drops 2 projectiles but before it drops a third, being careful not to advance RNG otherwise. Exit the stage and go to either 3-1, 4-1, or 4-3 to combine with stone by putting ice in Kirby's mouth and spitting it out, not throwing it. Swallow the ability star and exit the level. At this point the RNG value will be correct and 2-3 can be practiced.

Don't use curling stone when entering the level to make it easier to freeze all 4 Boneheads. Freeze the next bonehead but let the one after it live. If any mistakes are make for the rest of the room, the Bos might advance RNG more than they're supposed to. After jumping off the star block and curling, continue that curl all the way down the skeleton's spine until the block that requires stone is broken. Curl to defeat the Gabon, then start running and don't use curling stone until Kirby is part-way up the slope at the start of the skeleton's jaw. Continue that curl until back at the opening in the spine so that the Bos are despawned. Leave the Bonehead that already activated once alive, but freeze the other one. Continue through the room quickly, not freezing any Bos. RNG should not be purposely advanced for the rest of the level.
