Puyo Puyo Fever (Dreamcast)

Puyo Puyo Fever is the fifth entry in the Puyo Puyo series and the second one to be handled entirely by Sega. Feeling the series was getting a little stale, they decided to ditch the current cast (sans Arle and Carbuncle) and introduce a whole new cast, leaving us with a cast of characters including gay skeletons, stuck up bitches, and smartasses. Oh, and it's been released on virtually everything that is capable of playing games.

Unused graphics
For a game with not a lot of graphics, there is surely a whole ton of them that go unused.

Arcade leftovers
Some textures from the arcade version were left to go unused in the Dreamcast version. All of these have an English equivalent as well, which not only goes unused but was never present at all in the arcade version.

Australian version
The text "AUSTRALIAN" and "VERSION" is never used. Additionally, most of this image goes unused in the Dreamcast version; only the big blue text is used.

Cutscene backgrounds
Every cutscene in the game contains a low quality low resolution background in the same file as the other textures used for that cutscene. Needless to say Sega decided that they were crappy too (!) and instead used higher quality backgrounds stored in a separate file. While most of these backgrounds are the same, some of unused ones use a filter that can be seen in some pre-release screenshots.

Menu
An earlier version of Amitie's main menu image is present in the game files. The final version just uses her character select image for this task.

Parental advisory warning
This image, typically used by Sega arcade games released around the time of this game's, is never used. Kind of ironic that this game is suitable for all ages though, considering the DS version was tagged for mild language.

Other
This texture is only present in the arcade version's game files and even then it goes unused. The graphics seen at the bottom are actually from Puyo Puyo~n. It's possible the game may have used some graphics from it until new ones were made.

Unused animations
Oshare Bones has an animation that goes unused in all versions except for the GBA and DS versions. If used in-game it would have appeared as his final chain spell. It's possible it may have gone unused due to a mistake. In the game, each character has their spells attached to an animation; usually they go 1 - 2 - 3 - 4 - 5. Oshare's for whatever reason is 1 - 1 - 2 - 3 - 4.
