List of unused/prerelease content in Chuhou Joutai

This is a list of pre-release and unused content in Chuhou Joutai.

Early iteration
The game was initially going to be developed as a crossover between Bandai Namco Entertainment's  and Kadokawa's Lucky Star franchises. The game was eventually retooled as an original IP after the development team could not secure the rights to use those characters while retaining elements from the initial concept.

Visuals

 * In alpha builds of the game, the intro was different with different slides.
 * The title screen was different.
 * The character graphic displayed on the screen before a boss fight began was originally much grainier before it was made cleaner in the final release.
 * Like in the early Touhou Project games, after a boss or midboss was defeated, every individual bullet would display the number of points the player earned. It was showcased in prerelease gameplay footage before being dropped due to memory limitations that resulted in frequent lag or worse, softlocks.

Sound

 * The original version of the AdLib/SoundBlaster soundtrack actually used the YM-3812 chip used in those sound cards. However, that soundtrack was not very well received by initial playtesters and was updated to be more "blast processed" in the final game.

Content

 * In earlier versions of the demo, later stages were not present.

Unused content
Unused content within the game can only be found through datamining, and cannot be found within the regular game.
 * The "star item", which originated from Touhou Project, was going to be in Chuhou Joutai but went unused for unknown reasons. Based on the appearance, it was likely going to serve the same purpose as its other counterpart after a boss segment is depleted or even when a bomb is used.
 * There was going to be a CRT feature that would display the game with a CRT effect to give the illusion of playing the game on a CRT monitor. It was scrapped for unknown reasons.
