General Information

Chrono Cross

1. In General

The world of Chrono Cross is built out of a series of rooms: locations with a single backdrop that scroll as the player moves around them. Each room can be divided up into three files containing various kinds of resources: a script.cpt, a rgfx pack, and a drp. Examination of 7 samples suggests that the drps contain graphical resources pertaining to animated sections of the background (tim textures, meshes, and in one case models) and information for using/assembling them (timinfo, types 10, 12, 16). One drp examined was empty.

2. Standard Locations

Individual rooms can be blocked together to form areas (villages, dungeons, etc.); in most cases the location files for Home World and Another World are interleaved in the same block (for instance, the ground floor of Serge's house in Arni(Home) is followed by the ground floor of the same house in Arni(Another), then by Serge's room in Arni(Home), etc.). Exceptions are few; they include the Zelbess/Invincible, the Dead Sea/Sea of Eden, and locations which either exist only in one world or are the same in both worlds, such as the Bend of Time.

Viper Manor is probably the largest single area, with ~60 rooms and nearly 200 files.

~CD2 replaces parts of the Dead Sea and some endings available only on ~CD1 with parts of Chronopolis, most of Lucca's House, and endings available only on ~CD2.

The Darkness Beyond Time has no room data as such—it consists only of a battlefield and a scripted cut-scene, both of which are probably called from the Opassa Beach fieldscript code.

3. Scenes

"Scenes" are cut-scene "locations", viewed only once per game, with strictly pre-scripted actions and dialogue. For some reason, the Radius/Garai/Masamune scene seems to be missing—either it's mislabelled, or it's embedded inside another room.

4. Alternative Endings

Alternative Endings: any ending other than the basic "good" one. The Developers' Ending and Return of the Downtrodden are found only on ~CD2, and most of the others are only on ~CD1.

5. Miscellaneous

Presumably, it's something about background image display or camera action that causes the Game Over screen to need to have a location defined for it.

6. Removed rooms

These rooms are the removed rooms 0-7 which, under the Debug Mode, cause crashes and/or black screens. These probably made up the entire multi-room debug area.

As these files are empty, each is exactly one sector long, beginning at sector 7092 and ending at 7115.
