Pop'n music 4 Append Disc (Dreamcast)

pop'n music 4 Append Disc (Dreamcast) The second of two pop'n music Append Disc releases, which require pop'n music 2 to load. It was also released for the PlayStation.

This game, alongside a port of Silent Scope, marked Konami's final titles for the Dreamcast.

Unused Graphics#

Interface Repository#

POP_OPD.BIN contains many graphics associated with the game's interface, such as backgrounds and UI elements. It also hides several unused graphics, noted below:

At offset 0x455BAC, there is a sheet of genre graphics to be displayed in the records and total results screens. One of the slots is for a song with the genre CRYSTAL, which does not exist in this game. However, a song with this genre, Escapes from your love, would later appear in the PlayStation release of pop'n music 5.

At offset 0x457BCC is another genre graphic sheet, which has two placeholder slots. These were meant for HYPER charts for the songs ENAMORADA and Taiyou ga mitsumeteru, though they don't have them in this game.

At offsets 0x55EB24 and 0x57C988 are more placeholder graphics for these two charts, this time for the song results screen. These graphics refer to these charts as "Yokohama Hyper 1" and "Yokohama Hyper 2", respectively; "Yokohama" refers to the former KCE Yokohama subsidiary, which developed the pop'n music PlayStation and Dreamcast ports. By the time this game was released, however, it had merged with KCE Sapporo, becoming KCE Studios.

At offset 0x972278 are placeholder slots, labeled from 1 to 64.

At offset 0xF1D2A4, which has some character icons, are several more placeholders:

Character Repository#

POP_SRN.BIN mainly contains graphics associated with songs and characters. Much like the interface repository, there are a few unused graphics which refer to ENAMORADA and Taiyou ga mitsumeteru‍ '​s unused HYPER charts:

The files located at 0x925500 and 0x92D520 contain tiles for the songs' titles as seen during gameplay, which label these entries as "Yokohama 4H" and "Yokohama 5H". Their respective palettes and tile arrangements can be found at offset 0xD0741E.

The files located at 0xA8DAA0 and 0xA95AC0 contain tiles for the song genre graphics as seen in Practice Mode. They label the songs as "yokohama 1" and "yokohama 2". Their respective palettes and tile arrangements can be found at offset 0xD0AF3E.

ABSTRACT#

The ABSTRACT.TXT file, visible when loading the game's CD in a computer, has some text about... dolphins?

   はたしてイルカは、深海でも生きられるのでしょうか？ ～

   ・・・

～ 気付いたら、イルカのスピードが上がってる！？
                                イルカってば速すぎ･･･ ～

   ・・・

          しかし、潜行が止まる事はなかったそうです･･･ ～

   ・・・

～ イルカの前方に激流が･･･！
                         イルカの正念場と思われます！ ～

   ・・・

～ 調査隊の報告によると、第一次潜行は無事に達せられたようです！
                         現時刻をもって、Ａ作戦を終了とします。 ～

   ・・・

"Dolphin Diary"

~ Right now, the second dolphin is in hiding!
   Can dolphins survive in the deep sea? ~

   ・・・

~ If you notice, the speed of the dolphin is increasing! ?
                                Dolphins are too fast...

   ・・・

~ Report! It seems that Dolphin's combo was interrupted at 24 combo.
          However, it seems that the infiltration never stopped...

   ・・・

~ There is a torrent in front of the dolphin...!
                         It seems to be a critical moment for dolphins! ~

   ・・・

~ According to the survey team's report, the first dive seems to have been successfully completed!
                         Operation A will end at the current time. ~

   ・・・

~ Q: Dolphin Corps, how are you feeling right now?
                         A "Dokkin Bakubaku!" ~
・・・

~ Misinformation creates chaos on the front lines!
                         "Information analyst K, what are you doing!?"

   ・・・

~ A typhoon is approaching!
     I don't know if it affects the deep sea where dolphins live, but it's kind of mental. ~

   ・・・

~ Apparently, the P group of the detached force crossed the final barrier safely,
     It seems that it will move to the third submergence. ･･･ I pray for good luck ･･･. ~

   ・・・

~ It seems that D group will rush into the final barrier from now on.
     If you can pass without incident, this diary will not be written after that... ~

   ・・・

"Dolphin Diary Future Edition"

~ After all, there is only the final front, and it is forced to struggle.
                       I was prepared for it, but to this extent...! ~

~ ･･･ It seems that I managed to make it in time.
      With the success of the third dive, this mission will end.
      Now I just want the dolphins to rest in peace...


                    "Miracles happen...!"
