# GC-style song selection
|
|
|
|
Running the stage player without a stage path opens the graphical song
|
|
selector backed by `data/boot/stage_param.dat`:
|
|
|
|
```sh
|
|
./tools/run_stage_player.sh
|
|
```
|
|
|
|
Passing a stage remains the direct reverse/debug path:
|
|
|
|
```sh
|
|
./tools/run_stage_player.sh GC/data/stage/ac_oshama_hard.dat
|
|
```
|
|
|
|
The selector renders the original English `selectmusic2` and `selectmode2`
|
|
RVB/MTX scenes. Exact task flow, coordinates, animation bindings, and the
|
|
container reverse are recorded in `docs/re_gc_menu_exe.md` from
|
|
`game471.exe` itself.
|
|
|
|
What is already wired:
|
|
|
|
- the original portrait 720x1280 `SELECT MUSIC` and `SELECT MODE` scenes;
|
|
- original MovieClip frame labels, display-list depth updates, transforms,
|
|
alpha fades, and RGB color transforms;
|
|
- the original `common_eng` controller HUD and animated Yume navigator scenes;
|
|
- the executable's purple-to-pink background strip, rotating wire sphere,
|
|
translucent menu geometry, and `balloon.dds` lower backing layer;
|
|
- genre filtering from the catalog genre byte;
|
|
- the twelve dynamically linked `mc_music_link`/`mc_index_link` carousel
|
|
slots with their executable positions and opacity table, including original
|
|
`s_j_eng.dds` genre headings as real scrolling entries;
|
|
- title rows, jacket, source and artist cut directly from each original
|
|
`data/stage/2d/<imageKey>_menu.dds` atlas;
|
|
- SIMPLE/NORMAL/HARD/EXTRA availability and selected-state MovieClips from the
|
|
same catalog;
|
|
- separate select-music and difficulty states, matching the task transition
|
|
proven in the executable;
|
|
- launch through the selected difficulty's exact `ac_*` stage ID.
|
|
|
|
Entries are included only when both their menu atlas and at least one local
|
|
stage `.dat` exist. This dump currently yields 887 playable songs from the 924
|
|
master catalog records. Only the visible carousel window is uploaded to the
|
|
GPU, rather than all jackets at once.
