Version Differences

This is a sub-page of Deltarune/Chapter 2.

Platform Differences#

Borders#

As with the console releases of Undertale and the Chapter 1 demo, the console release of Chapter 1&2 contains various borders that are dynamically switched out Super Game Boy-style based on which area of the game the party is present in. In addition to the three borders included in Chapter 1, Chapter 2 includes three new borders themed around the Cyber Field, Cyber City, and Queen's Mansion areas.

[Press F1 For] HELP#

Spamton's battles feature an Easter egg based on pressing the F1 key: during both his normal and NEO fights, it will summon Spamton angels that heal the party (which can only be done once per attempt). While these Easter eggs can be triggered on the home console versions with a USB keyboard, the player can also activate the feature with a controller by clicking the right analog stick.

Regional Differences#

Librarby Interior#

English	Japanese

Just like in Chapter 1, the Teenz-Own banner inside the Librarby is translated to Japanese.

Queen's Visor#

Some of Queen's visor messages are replaced with Japanese-language equivalents; most of these are written in katakana, tying in with Queen's technological theme.

Cyber Field Screens#

Several of the screens that appear during Queen's first appearance and in Cyber Field are translated into Japanese.

Cyber Field Keyboard Puzzles#

This page or section needs more images. There's a whole lotta words here, but not enough pictures. Please fix this.

"AGREE2ALL" is changed to "YEEES2O!!" (with the letter O, but Queen interprets it as "YEEES2〇!!" and then as "YESに丸!!" YES ni maru meaning "Circle YES"), and "GIASFELFEBREHBER" is changed to "SUFUGIOROTENIPEKENAMO".

Annoying Mouse Room Signs#

English	Japanese

The neon signs in the Annoying Mouse Rooms are translated into Japanese.

Spamton#

Watch on YouTube

The sales pitches that appear as one of Spamton's attacks in his first fight are translated into Japanese and use a thinner font (matching the one used for standard in-game text).

Kris's Mansion Room#

English	Japanese

There's only one pixelized Toriel playing the piano in the Japanese version, probably because the "video game piano tutoriel" pun wouldn't make sense in Japanese. Notably, this is the only actual layout difference between the two languages.

Rouxls Kaard's Speech Bubble#

English	Japanese

The "Hey" speech bubble that Rouxls Kaard generates in-time with the accompanying voice clip in "It's Pronounced 'Rules'" is translated into Japanese.

Pipis#

English	Japanese

The crudely-drawn sign that appears when Spamton NEO starts his Pipis attack and when fighting Pipis enemies is translated into Japanese.

Spamton NEO VCR icons#

The mock VCR HUD icons that appear during Spamton NEO's ultimate attack are translated into Japanese.

Notably, the Pause icon adds a pun in Japanese, with teishi ていし "stop/pause" written as テイ死 using the kanji for death with the same pronunciation, rather than its normal kanji. Additionally, the Record icon, 殺エイ中, is a pun on 撮影中 satsueichuu "now recording", with satsu replaced by 殺, "kill". Both puns tie in with Spamton's affinity for making death-related wordplay in the Japanese script, replacing instances of "dai" (だい) and "desu" (です) with the English words "die" and "death" (e.g. writing "daisuki," だいすき, as "dieすき") and formatting the first-person pronoun "watakushi" (わたくし) as "わた94" (playing off of how in Japanese, the numbers 9 and 4 can be read in ways that are respectively homophonous with "pain"/"suffering" and "death").

TenderGoodbye.EXE#

English	Japanese

Queen's "Tender Goodbye" is translated in the Japanese version as "Bye Bye Genki De Ne." As such, the filename banner that appears when she activates it is rewritten to reflect this; unlike the other translated graphics, this one uses Romaji.
