The Mutation survey after 248 looped at the party call (menu 68) in five starts and stopped at the gate hack in two. Both led back to the port.

Calling a member by address

In a town, PERSONAL, Party, Add called the member and showed his greeting, but he never joined. ccThPartyAdd asks ccParty::AddMember, and the port's party_add only took a character an event had registered. A member called by address is not registered: the game's inviteSpc (gcmn 0x005a08e0) makes one, and that branch was not ported. The field-walk page had it as a known gap: "no event script makes one". The party menu does, though, and every player calls members that way.

What inviteSpc does for an unregistered id, from the disassembly:

1. EntrySpc, which gives nothing when the registry's five slots are full.
2. The character's file is queued (spcTempFileList type 9, ccLoadFLAddOne, then GetCCSAdrs into the registry's +0x20).
3. The character table's equipment is copied into the registry (+0x10 - +0x16), then ChangeWeapon.
4. The character stands at StartPos[slot]. ccGetChgatePosDirc copies the Chaos Gate's +0x40 position and +0x60 heading. The angle is the heading plus inviteOffsetTbl[slot] (gcmn 0x00654130: 0, 0x2000, 0xe000, 0x4000, 0xa000 in 16-bit turns). It goes through DEG2RAD and then fptosi before sinf and cosf, so only whole radians reach them. x gains 150 sin, y loses 150 cos, and he faces half a turn from the gate.
5. The registry's partyFlag is set to 1, ccSpcStart[id](slot, 0) builds the character, and a new ccAI takes ChangeMode(1).

World::party_add now does this through invite_new before AddMember: entry_spc, build_spc, and the gate placement with the same truncation. The equipment copy is not ported, because the port builds the character from the save. A field or dungeon still cannot build one. The docs say both.

The hacks at a start

A story start replays the events before it, but not the fights. Infection's starts are given the cores for its three listed hacks (HACKS: events 18, 25, 30). Mutation's areas 44 and 45 need cores that no replay gives, for example two of core 1 for area 45 at event 105. fights now tops up the cores for every protected area that the start's own event goes to (goes: the fields of its in_field, in_dungeon and field scene settings, and its gate_words areas), unless the area is already hacked (protectArea). Infection's list still applies as before.

The autopilot

• Members. An in_party condition is a want only when the same event also refuses without that member (not_in_party names him). Event 105's blocks 5 - 13 are lines for whichever member came along. Taking them as wants had the autopilot calling nine members in turn.
• The party before a warp. Going out to an area, the free slots are filled first (companion) with members who have an address and answer calls. One who knows Rip Maen comes first, then any healer.
• Field 45's entrance holds the door under a roof: the ramp runs down west from the middle to the doorway's floor at z -465. land finds only the highest floor, so no door cell was found. The planner now keeps every floor that a line straight down meets (the height map's ground where no model floor is). It walks floor to floor, no more than 120 up or down. A door is any floor with bit 0x80000.
• A room whose doors stay shut. Once the walker has put Kite in the same room and he is still stuck there, it fights every foe in the room, not only those within 600. Its magic portals may then be opened too. An event's entries hold the doors (CloseDoor) until they fall.
• PINEY_SURVEY_GOD runs a survey with the console's god: the party is kept at full HP and SP in the fields and dungeons. Without it, 105's floor 2 (two Great Sled Dogs at 1330 HP, a Phalanx and a Hysteria, level 31 - 32) beats the level 26 - 30 party the start brings. The foes' HP that climbs mid-fight is the game's own: the enemies cast Regene, and setSkillRate weights it up 1.5 times.

The survey (60000 frames a start, PINEY_SURVEY_GOD)

• Finish: 102, 104, 105, 109, 110, 114. 105 runs from the board through Carmina Gade, the calls, area 45's hack and its three floors to the desktop.
• In their dungeons at the end: 107 (field 46) and 112 (field 49) circle CHAT's member menu (71); 111 (48), 113 (50) and 115 (52) are still walking.
• Waiting: 103 in its town, 106 on the desktop, 108 on the top page.
• 116 plays its staff roll.
