This page details one or more prototype versions of Undertale Yellow.

This page is rather stubbly and could use some expansion.

Rewrite blurb
v1.0 - v1.1 differences
Potentially unused enemies, obj_messenger (has battle room) and obj_cactony
A lot of the sprites, dialogue, as well as the background in Dalv's fight is different (and Handshake isn't highlighted yellow)

The Demo of Undertale Yellow was released on November 30th, 2016. It only covers the Dark Ruins, but as the release dates of this and the final version are 8 years apart, there are still plenty of differences to unpack here.

General Differences#

The Demo uses an engine created by then-head programmer Spasco. The combat portion was previously released as a part of Annoying Dog fight, another fangame "made by Spasco in 3 weeks in 2015 for fun".
- The final game was partially recoded with mysteryracer's engine from Undertale Customs; some code such as UI objects and cutscenes from the Demo remained mostly intact.
- The Demo's GameMaker version was, according to the general info chunk, Studio 1.4.1760, while the final version bumps it to at least 2023.4.

Cutscene Differences#

Intro Slides#

Most slides were redrawn, and the wording got slightly refined.

Demo	Final

Here, the Demo has a primitive animation where both sides move a bit behind slowly; in the final version, the 3 sub-slides shown above are revealed gradually.

Audio Differences#

Early	Final

The instrumentation of "Once Upon a Truthful Time" is closer to Undertale‍ 's "Once Upon A Time" in the final version.

Early	Final

"Fallen Down (Yellow)" has slightly different instrumentation and is shorter.

Early	Final

"Ruins (Yellow)" has different instrumentation as well.

Early	Final

"Enemy Retreating" has much less refined mixing, different drumming, extra wind and cymbal sounds, and missing pitch bends.

The way it speeds down is different, and it also plays on the But Nobody Came screen.

Kill Count	Demo	Final
13	1x	1x (7/7)
14	0.9x	~0.86x (6/7)
15	0.8x	~0.71x (5/7)
16	0.7x	~0.57x (4/7)
17	0.6x	~0.43x (3/7)
18	0.5x	~0.29x (2/7)
19	0.4x	~0.14x (1/7)
20 (But Nobody Came)	0.2x	`nobodycame_yellow` plays instead

The Demo has a unique medley for its credits screen, known as "To Be Continued." For some reason, it was apparently rendered with Adobe Premiere Pro.

Graphics Differences#

Toriel#

Proto	Final

The colors of her clothes are a little darker, and also the end of her scarf is at the back instead of the front.
