Pop'n music 12 Iroha (PlayStation 2)

pop'n music 12 Iroha (PlayStation 2) A home port of Konami's pop'n music 12 Iroha arcade rhythm game. With it, the original release's NET Taisen mode was adapted into Taisen mode, in which the player battles against two other computer opponents.

Unused Graphics#

NOTE: None of the graphics listed below have proper filenames; the names are given based on the order in which they are present in IMAGE.DAT.

Unused Song Leftovers#

Throughout the game's archives are leftover graphics for several songs that are normally unplayable. Save for a single song, character data will not be covered here.

Atsushi Shindo#

Quite notably, all of Atsushi Shindo's songs that appeared in the pop'n music arcade titles have their backgrounds stored within the archives, long after they had been removed due to plagiarism allegations against their composer. They also have artist tags (save for Kimi ga suki da yo ~mamotte mamotte ageru kara) present in File 56, though they have been blanked out.

File 437 - Nanka hen da!

File 438 - Kimi wo kowashitai

File 439 - Kimi ga suki da yo ~mamotte mamotte ageru kara...Folky Version

Title Tags Only#

There is a single odd song within the title tag graphics within File 54. The song in question is BREAK DOWN!, which was, at the time, available through the ee'MALL service in arcades, and did not appear in any home releases yet.

"Meitantei Conan" main theme#

This song, which made its first appearance in pop'n music 12 Iroha‍ '​s original arcade release, does not appear in this port. Despite this, it still has related graphic files within the data, the most of any other unused song. This also includes icons for its character, an exclusive variation of Nyami.

Unused Characters#

There's also files for five unused characters:

LISA [5]#

This character is known to have appeared in three songs: Dounacchattatte from pop'n music 5, Shiritori from pop'n music 8, and brave! from the ee'MALL service. The latter appeared in the previous home release, so this is likely to just be holdover data from there. Contains complete data.

File 350

Poet [4]#

This character is known to have appeared in two songs: Over The Rainbow from pop'n music 4, and Sorekara from the PlayStation release of pop'n music 5. Only contains icon and in-game sprite data.

File 339

File 340

Bronson [9]#

Only contains portrait data for the character's 2P palette, found at File 156. At the time, it was used by the ee'MALL song Baribari boogie ~namida no fruit punch~.

YUKI [4]#

Only contains portrait data for the character's 2P palette, found at File 245. As this palette is not known to have been used by any song, its presence is a mystery.

Taro&Okon [4]#

This character is known to have been used in a single song: Ai kotoba from pop'n music 4. Only icon data exists, found at File 4.

Enjoy Mode Jackets#

The archive that contains the jackets that would normally be seen in the game's Enjoy Mode, File 53, has many graphics for unseen songs. They are likely leftovers from the game's arcade release, given the presence of some songs that never appeared in any home release.

Tokyo Game Show 2005 Leftovers#

Two leftover graphics from a build of the game shown at the Tokyo Game Show 2005 event can still be found unused.

File 8
This graphic would be displayed in the title screen.

File 212
This graphic is stored alongside the character portraits.

More Arcade Leftovers#

More leftovers from the game's arcade release.

Title Screen#

These graphics can be found in File 8.

NET Taisen Leftovers#

While the NET Taisen Mode was reworked into Taisen Mode for this release, assets for the original can still be found within the archives.
