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

Some annoying backtracking, but this uses a decent amount of glitches (especially at the beginning) and shows very precise movements and strategy. I vote yes.

Merlin ate too much acid as a kid. I think this TAS is enjoyable. The run, the game and the antics are pretty charming. The music is enjoyable, even if the sound effects are a bit jarring. Overall, this project turned out a lot better than I had envisioned. The pace could be slow at times, but I think the glitches more than make up for the slow parts. Nice job.

Amazingly well planned and executed run. Congratulations for finishing it, DaTeL237! Your TAS magic is far beyond the ordinary magic presented in the game. Note: I made a savestate during playback and the movie desynched soon after loading the state. Nevertheless, I strongly recommend making a savestate at frame 126 000 and replaying the mine cart glitch a few times. It is one of the craziest things I've seen happening in a TAS. Technically, it seems like a simple TAS trick, but visually it is a brilliant magic performance.

Thanks, yeah the run contains a lot of backtracking... try playing the game real time and suffer even more :)

Woot thanks. I had desynch issues when i used v1.51 as well, but after switching to v1.51+5 I never had a single problem anymore The minecart can be glitched in many ways... if only it were useful purposes :D I might do some short demos on glitches that weren't displayed

Yes vote as you may have expected. Special congratulations on beating all those route tests! You get the best ending skipping so many required items, which I didn't expect would be possible, though Westwood has no more prize T-shirt for you. :P EDIT:

I had a desync while watching this normally, sometime in the second trip into Rainbow Land. What I saw before then was pretty crazy, and had me laughing quite a lot. I'll hold off on voting for now.

That good to hear :) I was afraid the entertaiment value was going to drop below reasonable levels due to the game's pace

Here you go Feel free to ignore the logo, I had a brain fart of some kind. Anyway, any encoder may use this for publication. The logo's been approved by Bisqwit, if that's the concern.

Seems Young Merlin has more magic powers than he once thought ;) I enjoyed it and it did not even seem like 40 minutes had gone by. Yes from me.

Thank you, this desynched for me twice (first time was the 1st time in the water level and 2nd time was the 3rd time you went to the water level). Anyways, from what I've seen up to date, this is very well played. This game still gives me the creeps for some reason... when I was a kid I was terrified of this game :P

Thanks for voting in the new system everybody that did, it seems that this submission just missed the start of it and unfortunately missed out on some votes :P

This game could have been quite boring, but the glitches add quite a bit of entertainment value to the run. The purple blob turning into a woman who morphs into a man without legs had me laughing. The health management was excellent, especially while underwater. I did have a question though: At around frame 44,000, you cross a bridge without walking along the railing like you did earlier in the movie, making me think that you accidentally moved downward too far before turning right to cross the bridge. I'm assuming there is a reason for this, but it stuck out to me as somewhat odd. I had a desync at around frame 55,000, switched over to SNES9x 1.51 v5, and it got up to frame 58,000 before desynching again. I liked what I saw for the first 40% of the movie, so I'll try to work with my setup for a bit and see if I can't get these sync issues worked out.

Good to hear more feedback :) The first time crossing that bridge, Merlin is 'glitched' into a state where his position (as used by the game's collision detection) is not the same as his displayed position..... so technically I never walked on the railing, but it appears that way all other instances of crossing the bridge, the glitch is no longer active (it is fixed upon death.. inside the hedge maze) wish I could do something about the desynchs... all PCs I tried ran it just fine :X edit: just tried it on a fresh WinXP with newly DLed TAS, emu (1.51+5) and the ROM... worked all the way (didnt't use savestates ofc.. since the PC didnt have them)

I can't believe I watched this whole thing. I can't believe I watched every WIP of yours. I can't believe that I actually enjoyed it. I loaded up the WIP the first time(a while ago) and thought that this game couldn't possibly have any entertainment value. However, your input coupled with this game's great soundtrack made it a great game to watch. Question, though. Is walking upwards the same speed as walking up+right;up+left? I noticed you did it once(somewhere in the mines), but never again. I would have preferred to see that once in a while rather than Merlin just walking straight up(or down).

yes diagonal movement has the same unidirectional speed as going in one direction

Another video option. Pretty much the same as shinydoofy's. I was doing some unrelated testing and ended up with a passable result so sharing just because.) Never heard of this game before, but I was entertained for 40 minutes so good job :)

I found this movie rather dull. Not my cup of tea I guess. Seems like it has some nice strats/glitches/TASworthy stuff though. I rated it 4.1/7.5
It's hard to look this good. My TAS projects

Thanks for another encode, good quality imo. slight problem with it was that i couldn't "skip to X" in the second half of it, but that might have been my player/PCs problem

well, I watched this[encoded] many times and I thought I rated it, but no. 8,9 good music, good graphics, meh bosses, meh bosslaugh. I'd like a good explanation of just what the frell happens when you go off the tracks with the minecart though- you mention that cutscene canceling allows you to, but...

ok, thanks for feedback. At the mine carts, Merlin normally gets into a special state where control is not fully up to the player. By using the freeze-cancelling, this state is deactivated. In this particular case, movement control is not regained, but the option to toggle and use items is. I believe this messes up some part of the RAM... anyway, every item has now some awkward effect, most of them related to the intended mine cart behavior. The bottles seem to put Merlin back on straight track, facing left (not that there has to actually be track underneath him, else he crashes and dies)... this means that we can make him move right while facing left (which happens off-screen) The balloon appears to trigger a corner that turns from-facing-right-to-facing-up, however this only goes for the visual part... internally, Merlin moves on as he was, without checking any of the triggers (corners, bounce balls)

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.
