Full Unlock Code#
Imperishable Night follows up the previous two games with yet another full unlock code.

If done correctly, you'll hear the 1up sound, and the Extra Stage, all solo characters, and all practice stages and spell cards (including Last Word spell cards) will be unlocked for all characters and difficulty levels.

Unused Sprites#
Yukari doesn't move right or left during her Last Word.
Ran doesn't appear as an opponent in this game. Her sprites are stored in the same spritesheet as Yukari, that's why these sprites went unused.
Alice raising her grimoire/book.
Remilia doesn't transform into a bat during her Last Word.
Despite Yuyuko's Last Word being similar to her last spell from Perfect Cherry Blossom, she uses her normal sprites.
Unused Graphics#
Phantasm Stage Unlock Screen#
The unlock screen for Perfect Cherry Blossom's Phantasm Stage is left over from the previous game. However, there were phantasm stage sprites with a title matching with Sakuya Izayoi's last name.
Unused Grades#
Upon clearing a stage, you are given a grade depending on how well you did, and the higher the grade, the less time is added. ランク申 (Rank A) and ランク乙 (Rank B) are used and advance the clock by 30 minutes and 1 hour respectively, but the following two went unused:
- ランク丙 (Rank C): The clock advances by 1:30 hours. This was used in the trial version, but removed in the full version.
- ランク丁 (Rank D): The clock advances by 2 hours. Not mentioned in the manual at all. If it was used in-game at any point, Likely in the very early stages of the game (Early 2004).
Oumagatoki#
This graphic (逢魔が時, commonly translated as "twilight" or "witching hour") bears a striking resemblance to Perfect Cherry Blossom's 森羅結界 text graphic, which appears when a Supernatural Border is activated. A similar mechanic may have been planned for this game, too, but seeing as not even the manual makes mention of it, it was likely scrapped very early on.
Stage 2 houses#
Leftovers for a house exist here. Albeit just containing the roof texture. It is unchanged from Perfect Cherry Blossom Stage 2.
Music Oddities#
Extracting the game's MIDI soundtrack reveals several oddities:
- None of the Midi's play properly in Virtual Sound Canvas. It is unknown why, but its possibly related to ZUN getting Cubase SX 2 in early 2004.
- The first track in the soundtrack, track 00, is not the menu music but rather the Stage 1 theme, "Illusionary Night ~ Ghostly Eyes" and the menu music, "Eternal Night Vignette ~ Eastern Night", is track 01. The main theory for this is that since the song originally appeared on ZUN's album Ghostly Field Club, the song's MIDI was simply copypasted into the game's soundtrack before the rest of it was written. Although it would not make sense for him to not rename the midi instead.
- "幻視の夜 ～ Ghostly Eyes" appeared in WAV format in Ghostly Field Club. It contains some slight differences in the mixing. Although the instruments seem to be the same besides the Piano's being 001 --- St.Concert instead of 004 --- Bright Piano in the final.

- The numbering on the soundtrack skips over track 02, likely because the song that would normally go there, the Stage 1 theme, is track 00.
- th08_16.mid (Ending theme) has some notes after the loop, though they seem to be a copy of a main part.
- th08_19.mid (Mokou's theme) has an unused section of notes that play after the loop, they cannot be heard in game and can only be heard through a midi editor/DAW. They seem to make an ending to the song, Reminiscent to ZUN's Music CD Rearranges. Although when this song was rearranged in 2006, the ending part was still not included.
