Spawn

A small struct in static data that determines spawn locations, of size [2c]. There are two contiguous instances:
805b6ae0 | slave
805b6b0c | master

Layout

offset size description
0 [20] location (folder string)
20 [2] ? (resets to 00 0F)
22 [1] room
23 [1] layer
24 [1] entrance
25 [1] night? (iff == 01)
26 [1] trial? (iff == 01)
27 [1] ?
28 [1] ? (resets to FF)
29 [3] _

During a reload, the data from master is copied over slave. The layer in master is the forced layer – if it’s 0, the actual layer is computed from story flags and stored at the layer in slave.

Reloader

Reloader  
Location (variable)
Pointer 805789f4 (static) | aka r13 (=8057c6a0) - 0x3cac
Size 0x2b0 | confirmed in 801b9760: _Heap::allocReloader()

Also have a nearby helper variable:
805789fd [1] (static): reloadType. All reloads use the spawn data from the master spawn (above), but load different position and angle data from file FA. This data comes in triples, labelled type-1,2,3 in file docs.

The function 80063640 | determineReload (partial decomp here) uses this flag to select data to load, then clears the flag.

Files store triples (type-1,2,3) of Spawn data (area, forced layer, entrance, etc.) as well as position and angle; both Spawn and position+angle obey these dynamics:

Reloader Data

offset name size description
23c reload trigger [2] normally 0x2bf; triggers reload when set to 0x5
240 ? [2c] a Spawn object, unknown use
26c type-0 pos data [e] [x,y,z,θ] (float × 3, short): Link position used during a t0 pos load
28b type-0 cs flag [1] if 1, force cutscene on type-0 load
2a0 type-0 pos flag [1] if 1, force position on type-0 load (and use data at 26c)
2a2 save-prompt flag [1] if 1, display save-prompt on next reload

Functions

801bc080: assignSpawn. Directly sets values in a Spawn object (the first arg). Breakpointing this shows some of the dynamics between the two Spawn objects and Reloader.
