In the Groove (Arcade)

Chris Foy and me. The defining rule of this game seems to be that the developers never threw anything away. Things either got replaced or were left untouched.

Duo mode
Older development screenshots show a number of modes that cannot be selected in the final game as options. Duo mode, where two players each have unique charts, was one of these, and it seems to have survived long enough to actually have some work done on it. There is an incomplete set of mode selection graphics, and even some charts, still in the game data.

The following is a list of all of the remaining Duo charts. There are no Duo Expert charts present.

Select Play Mode
In the Groove has two completely different unused versions of the "Select a Play Mode" screen. Paradoxically, only the oldest one still works.

Earliest version (ScreenSelectStyle)
This is the oldest version of this screen present in the game data. Based on pictures released of various development versions, it probably was in use in mid-2003. All of the graphics specific to this screen still use the old gray-and-white style, and look completely out of place with the final UI elements. There's position data for a fourth play mode that isn't identified, as well as icons for several more.

Later version (ScreenSelectStyleNormal)
This is a later version of this screen made sometime after the redesign, dating it to early 2004. Trying to access this screen with no changes causes the game to crash instantly, as the screen type it uses was removed at some point. It can be made to load by tweaking the screen definition to use a closely related screen type. For the most part, it resembles a more rudimentary version of the final play mode screen. There are graphics for Duo mode, but they aren't enabled.

Select Difficulty
This screen actually wasn't shown in any screenshots, and had to have been abandoned pretty early on. It's probably about as old as ScreenSelectStyle. It was probably abandoned as a pointless feature before any pictures were released. "Chill", "Jam", and "Killer" were the original three difficulty names; they were replaced with the more obvious Easy, Medium, and Hard later. Expert wasn't available.

Unused noteskin
This noteskin is technically ITG's default noteskin, but the game forces the metal noteskin to be selected by default and this noteskin isn't available on the options screen. It resembles a rudimentary version of the final game's Cell noteskin, as well as the arrows in several very old screenshots.
