A GAPS item. The breakables' own code (ccGimBox::breakObject, their crush effects) and their guard were ported, but EntryBreakObjectMain was not, so no dungeon room had anything to break.

The game

DUNGEON::EntryBreakObject() (gcmn 0x005bff10) runs every time the party enters a room.

• The guard. It places nothing in the lake types, in game.field 14, or in a story room with an event.
• The calls. Otherwise it calls EntryBreakObjectMain (0x005bfc40) five times, with the patterns OBJ_0pr2*, OBJ_0pr4* .. OBJ_0pr7*. pr2 gets id 0. pr4-pr7 get the four gimmick rows a jump table gives the dungeon's type (@4166, two copies of one four-row table).
• Each object. EntryBreakObjectMain walks the room anm's objects that match the pattern (GetSubstAdrs). For each it takes the world translation and draws fieldrand(4), even when the id is fixed. It then makes a gimmick entry with entRoot 2 and land 0. Id 0 takes the random one of the four rows.
• Leaving. The entry control deletes gimmicks with that entRoot when the room is left, so they are made anew on each visit.

The port

• The dummies. DungeonArea::breakables_here(field, block) applies the guard and lists the dummies in the calls' order.
• The entries. combat::DungeonEntries carries the list with the dungeon's type. Combat::start_entries makes the entries after the idols, on every room entry, with one fieldrand shared with the boxes.
• The check. the_rooms_have_their_breakables walks area 26's dungeon, counting only once each room plays (not during the change's fade). Rooms (0, 6), (1, 2) and (2, 1) get two each, and event 29's room (2, 2), a story room with an event, gets none.

The same pass removed a stale Unknown in effects.md: Skeith's death effects (BeginDeadEffect, ccBossEffDead) are ported.
