For beatmania IIDX, Konami added two more buttons and called it a day.
Now that is complicated. Like... trigonometry. Haha.
Song Title Graphic Placeholder
Found at the very end of file SEL16.MGP is a placeholder song title graphic, reading "Fujii DX", which refers to Takehiko Fujii, who composed two tracks for this game.
Early Build Remnants
Several remnants of early builds still exist within the decompressed ISO file of version JAA, the game's initial release. All of these graphics seem to be dated around a month prior to the game's release. Note that the palettes cannot be truly determined for now.
File CONTI16.MGP is an early version of the assets seen in the continue overlays. They are very barebones compared to the final assets, present in file CONT16.MGP.
The font used in the name entry sequence was originally going to be hand-drawn, more or less fitting its background. This early variant can be found in ENT16.MGP, compared to the final file NAME16.MGP.
- LEVE16.MGP is an early version of the final results screen asset package. Compared to the final LEVL16.MGP, only the rainbow ranking text sprites are present.
- MAIN256.MGP is an early version of the Single Play gameplay HUD. The color indexes seem to be different from the final SMAIN256.MGP, although whether the palette is truly different cannot be known yet.
- TECHNO.MGP is an early version of the overlay sprite sheet for the song special energy. Although it lacks many overlays present in the final ENERGY.MGP, the available ones don't seem to be different from the final.
Extended Intro Sequence
The game's opening FMV is significantly longer than what is visible in-game, about twice as long in fact. This can be seen by either playing the video in the test menu or by taking the Video CD the movies are stored on and playing it in a separate player. This applies to substream and 2nd style as well since they use the same intro sequence.
|Video as stored on disc||Video as seen in-game (starts at 0:26)|
At the beginning of the game's HDD data, the following credit can be found:
At the time of beatmania IIDX's release, Youhei Shimizu worked for Konami as a sound programmer, and was credited on this game as such. GQ863 is the model for beatmania IIDX.
The game's build date can be found in the title of the game's uncompressed ISO:
Two known releases of the game exist, officially known as JAA and JAB, respectively. The only difference seems to be on the song flo jack, where it was renamed to The theme from "Flo-jack". This change is reflected on its splash and song selection screen graphic.
