Backup entity and game state walking the entity tables at StateData_SimpleEntities / StateData_Boney.

|
Measure and copy Boney's complex entity state into the backup buffer at Buffer_EntityStateBackup.

| 44991 | INC DE | Advance the pointer in DE by one. | ||
| 44992 | LD (29351),DE | Store DE in Pointer: Entity State Backup End (Pointer_EntityStateBackupEnd). | ||
| 44996 | PUSH DE | Stash DE on the stack. | ||
|
Measure and copy the task/game-status block that follows the entity backup.
