NPCMovementScriptDex

This article is incomplete. Please feel free to add any missing information about the subject. It is missing: Some scripts function differently depending on where the player is.

This is the NPCMovementScriptDex about glitch CC57 scripts. CC57 (both Red/Blue and Yellow) is wNPCMovementScriptPointerTableNum. This article lists various glitch effects by index number.

Many of the "freezes" seem to be the common bar freeze or "rst $38" freeze.

CC57 scripts will typically disable talking to NPCs or entering battle.

Pewter City

As tested just in front of the Pokémon Center.

00: Valid (player not being guided)/does nothing
01: If the player locks it during guidance it will cause the guide to walk off to the left. Otherwise, lock up controls for a while, then Fly away to Red's house 2F, then ACE (CD3F) if ret unknown opcode 0xD3 at 2:4E40 followed by a corrupted stop (10 07). If skipped over game may still freeze.
02: Valid (Pewter Museum guide script) but otherwise may result in ACE (C43A)
03: Valid (Pewter Gym guide script) but may freeze the game otherwise

In Pokémon Yellow

Pallet Town

As tested just outside of Red's house in Pallet Town.

00: No effect
01: Unknown/seemingly nothing happens
02: Freeze
03: ACE (D0B2)
04: VRAM execution (froze at unknown opcode at 8CFA)
05: Seems to corrupt the map blocks to some not normally available blocks when the menu is open. The first two sub-tiles on the top-left block are sourced from B:4602 and B:4603 for block 00 (continues up to B:55F2 for block FF) (might be in between B:45BD DittoPicBack and 0B:4609 MeowthPicFront), because these are written to C50A onward (near C508 wAnimatedObjectsData), which is then written to C3A0 (top-left sub-tile), similarly [B:4603(+)([D35E]*10] is written to C50B, which is then written to C3A1 (second sub-tile from the top-left) and so on. It is exploitable for a practical use, but redundant for just using a regular Mew LG. Block 0x4B has a 0x15 sub-tile (Mew) in alignment for LOL glitch. Block 0x39 also contains a 0x50 sub-tile.
06: Unknown/seemingly nothing happens
07: Freeze

11: Freeze
12: Locks player, invisible text box with Start menu open, pressing A or B freezes the game, other buttons seemingly do nothing

41: ACE (F002)
42: ACE (EA7C)
43: See 3E
44: ACE (CDD0)

62: Freeze
63: ACE (FA86)
64: Seems to corrupt map blocks like 05, 10, 16, 17, 1B
65: This behavior is a little like 3E but more events happen; after short while player warps to Saffron City, then Sea Route 19, then a Route 2 gate (0x2F), then the player does a warping animation and rises up the screen looping around seemingly infinitely (similar to the moving down seemingly infinitely in 3E) 
66: Freeze
67: Lock up controls with invisible menu and Start menu (lock up but strictly not a freeze?)
68: Freeze (00 27 39 90 3E 80 corruption pattern)
69: Walk down on the spot and constantly corrupt the screen. When done from outside of Red's house 1F may enter it (negating the Red moves down the screen and loops effect later). Eventually get Safari Zone game over message, where the effect repeats, but strange warps happen. Game eventually freezes or loop down screen effect returns. Very fun but not sure if can be manipulated to avoid a freeze.
6A: Freeze
6B: See 67
6C: Freeze
6D: Freeze
6E: ACE (CDAF)
6F: ACE (C322)
70: Freeze

72: Walking lag glitch and eventual freeze
73: Brings up invisible text box with Start menu open. Pressing A/B  results in unknown opcode 0xE3 at A:78DC. If skipped over, freeze.
74: Seems to corrupt map blocks like 05, 10, 16, 17, 1B, 64
75: Freeze
76: ACE (D35D)
77: Partially soft reset game but the CC57 script is retained, resulting in a soft reset loop until the player waits on the title screen for that soft reset.
78: VRAM execution (froze at invalid opcode at 8498)
79: Invalid opcode 0xD3 at 0:48E0. If skipped over seemingly nothing happens.
