The animation notes' sounds (ccSeSetParamSPC, ccSeSetParamEnemy, ccSeSetParamInu) read setbl.cpp's tables. The port read Infection's for every volume. Two things kept it that way:

• The generator gave up where spc0SeData has no carried name (OUT and QUA).
• piney-audio's setbl read Volume::Inf into global statics.

Now each volume's own tables are used.

Where the data starts

spc0SeData is spcSeTbl[0], and it is the lowest row pointer on all four volumes:

placement::sound::setbl takes spcSeTbl[0] where the name is missing.

Outbreak's 21 party tables

The carried size of spcSeTbl is Infection's, 76 bytes (19 pointers). On OUT and QUA the words at the table are 21 pointers (ids 0-20, each a 14-row table) and then 3 NULL words up to the first enemy table at 0x00669140. On INF and MUT, id 18 is NULL, and one padding word follows.

The generator now runs each pointer table to the next object in setbl's data (a row a pointer names, the other table, or inuSeData). Padding is read as NULL, as the game would read it for an id past the table:

What differs

MUT's rows are INF's, shifted to its own base. OUT's rows differ from INF's:

• row 11 of each of the 18 shared party tables (Kite's is 106 on INF, 105 on OUT);
• the enemy tables, which start 44 rows later, behind the three new party tables, and change size (cateUndead starts 52 rows later);
• inuSeData, which is row 670 instead of 616.

QUA's rows are OUT's. Of 677 rows, only 21 differ: the pointer tables' words (rows 294-304 and 660-669), which hold addresses from their own base.

The readers

plans/volumes.md noted that the readers changed size. The instructions of ccSeOnPCStep, seHitAttr, ccSeSetParamSPC, ccSeSetParamPC and ccSeSetParamInu on INF, MUT and OUT were compared with addresses and labels stripped. They differ only in branch merging, delay-slot nops and stack slots:

• the footstep notes by id are the same (15: 63, 10: 61, 6: 64, 2/3/8: 58, 1: 62, 0: 60, else 61);
• seHitAttr's constants are the same (INF's 50 against OUT's).

The port's readers stay as they were and take the volume:

• se3d::spc_note, enemy_note and inu_note take a Volume;
• setbl::rows(v), spc(v), enemy(v), inu(v) and base(v) read each volume's setbl.bin once.

The callers pass the world's volume. DATA_VERSION is 14, since OUT's and QUA's builds had no setbl.bin. notes_are_the_volumes_own holds row 11 and ids 18 and 20 on INF and OUT.
