About the Game

A colorful 1993 SNES adventure in which Young Merlin explores a fantasy world to eventually free it from the Shadow King and his evil minions. The game features exploration, puzzle and fighting elements.

Approach

Memory watching was used continuously to optimize every action. Occasionally, TAS Movie Editor (v0.12) was used to alter the movie.
Merlin is slowed down by walking against walls so a large amount of rerecords went to simply avoiding wall collisions.
Damage boosting is used to save time wherever possible.
Lag is avoided wherever possible. An example; every attack with the Shooting Star introduces some lag frames, so the amount of shots is minimized.

Specific tricks used

Multiple occasions

Standing on the spawnpoints of items during cut-scenes to pick them up while locked. Thanks to klmz to pointing this out early on.

Thunder Pig sequence break

Taking damage off Thunder Pig allows Merlin to gain back control during the cut-scene.

Early Reflection Crystal

When Merlin is out of the camera's sight (caused by the Thunder Pig sequence break) , most triggers are not checked by the game, allowing merlin to collect the Reflection Crystal earlier than intended.

Lake sequence break

When merlin dies while he is frozen by the game (in this case, because he needs to wait for the Lady of the Lake to be finished) he will still have the 'ability' to press the Start button to break out of a Freeze state. This is used to break another cut-scene and collect the wrench in the meantime (two cut-scenes get intertwined here). Damage is taken spread out over several moments to initiate the sequence break as soon as possible.

Early cave herring

The creators intended the Air Bubble to be a required item for collecting the Cave Herring (without dying, in which event Merlin loses the Herring). By using a damage boost, the Balloon and trading some health for oxygen, it is possible to collect it anyway if Merlin starts with 9 filled heartpieces. This amount of health (starting with 3) is collected from a healing potion at the Tulip pond (+2), in the cavern (+1) and from another healing potion (+3).

Free Red and Blue Gems!

After using the Spring, Merlin is given a password, this is the game's way of saving process. By pressing the Start and then the Select button, this process is retrieved. Accidentilly, the creators assumed that the Bubble Wand and the Air Bubble would have been collected at this point and this information is incorporated in the password.

Filling the basins

It's possible to fill up the basins at the Underground Palace without losing any water by switching items at the right frame. The water is never used later on but the trick is performed anyway.

Dwarven Key warping

The Dwarven Key (four red arrows) is used to teleport back a few times to save some second.

Block pushing

A range of solutions exist for the block pushing puzzles, these are the fastest solutions I could find. Several Sokoban solvers were used to help finding these solutions. The 1-block-1-push 'puzzle' is done on the way back because doing it later would force Merlin to wait for the gate to open.

Swimming for a heartpiece

The heartpiece in the northern part of the underwater cavern is collected and deathwarped. The fastest way is to use the Air Bubble (fill air to 6 full bubbles) as soon as possible and take some damage to die earlier.

Rainbowland

A huge amount of possible routes is available, the taken one was thoroughly tested to be the fastest.

Comb skip

By using a damageboost off an enemy, the 2nd wooden heartpiece that is collected does not require the Comb item, saving a trip in and out of rainbowland.

Treetrump lady break

By using an item at a specific frame, the Lady of the Lake can be broken out of again. This also comes with the ability to break out of another freeze. The second appearance of the Lady of the Lake is broked with this ability, and this ability is available again due to it.

Ghostly minecart

By using the abovementioned press-Start-to-unfreeze action is used to drive the minecart through the wall and get back on track at the other side.

Spyder boss cut-scene

After the Spyder boss is killed, Merlin automatically walks to a fixed position and normally a cut-scene is then started. By getting entangled and dying in the web (only dying does not work), this automatic movement guides Merlin into the trigger to get out of that room. This timesaver has the side effect of granting Merlin semi-invincibility.

Thunder Pig cut-scene

After Thunder Pig another cut-scene is supposed to be started, but by taking damage at the right frame and using the hourglass to freeze time, this is prevented.

Bloop's body parts

By using the Mirror and some awkward movement, Bloop's body parts are manipulated to gather up in front of the door allowing a speedy exit.

Heart Locket usage

The Heart Locked unleashes a storm of thunderbolts in predetermined unmanipulable directions. This is why it seems impossible to kill the boss in 2 charges. The movie concludes with the activation of a glitch where Merlin gets teleported into the wall

So you go up-right through wall with aid of the balloon...and get back on track offscreen using the bottles? I'm curious because I can't see the track you reach which means I can't see a turn from horizontal to vertical if you hit one out there.
yes I got through the wall using the balloon. Then offscreen, there's a long stretch of horizontal track (see image below). By using the bottle while merlin is 'on' that track, he will actually get back on (and would crash into he gaps if I didn't tilt the cart, but you cant see this happening)... at this point, the camera is still fixed to the position where the balloon was used. The camera will return to normal (first having to travel a lot) when Merlin takes the northeast (or any) corner. Now, everything is back to normal and the freeze-cancel is no longer available.

Ah, thank you, that map is very helpful- the minecart areas don't have very much differentiation among areas for signposts in aid of mental cartography, at least without playing it.

Some parts were rather painful to pay attention to, however as others have stated there were a couple of really interesting unique parts. I particularly liked the Sokoban style puzzles even though those were perhaps the slowest part of all :) Sorry if this has been brought up before, but how would an any% run compare to this? 7|8

Thanks for feedback err, I think an any% run would still utilize the get-fish-without-airbubble break.... so I'd still have to get 9 heart containers and all bottles. then, the 7 pieces that would be skipped are probably: (numbers from here) 6. On mine cart track, by the horizontal jump. [~50s] 7. Northeast corner of the flooded cavern. [~28s] 9. In the entrance hall of the Dwarven Palace, use the Balloon by the exposed platform. [~12s] 10. Southeast corner of the first underground cave in the Rainbow World. [~15s] 11. West side of the field with all the Shroom Goons. [12s] 12. In the eastern section of field where Cinder is. [0 s] 13. Past a false wall in the southeast section of the final mine cart. [5-10s] total time saved: ~125s I think everything else would remain the same, perhaps a slightly better route through rainbowland may be possible estimated final any% time: 37:5X:XX

I apologize for not having gotten to this run yet. I have not had time to figure out my desync issues, but even if I had, I wouldn't have had any time to actually watch the whole run. I will put it on the top of my TAS priority list though. EDIT: I finally got around to watching this, sorry for the delay. I had to rely on the encode (thanks Shinydoofy!), because I could never get 1.51 to function properly. There were quite a few cool moments, but the constant backtracking got old after the first half of the movie, which lowered the entertainment value for me. Technically, it looked well done, although the first box puzzle seemed to include some unneeded moves (totally based on observation). In any case, I think it's a well done movie that belongs on the site.

Egad! What an ugly picture! I haven't watched the movie, but I could guess that: a) He got a nasty bee sting to his face b) He learned a helium spell but forgot to target properly c) He's doing a Cartman impression d) Someone told him how good a job the TASer did and his head swelled up with pride. At any rate, he ain't fitting in a door anytime soon.

Thanks everybody for feedback, and thanks to the site contributors for making it all possible btw I guess the closest answer would be (b), a helium spell :) I like the screenshot btw

Needless to say that it was the most amazing spell in this movie.
<klmz> it reminds me of that people used to keep quoting adelikat's IRC statements in the old good days <adelikat> no doubt <adelikat> klmz, they still do

I'd like to add my amusement that you prevent death by suffocation by filling up with helium on several occasions.
