|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.
As tested just outside of Red's house in Pallet Town.
Red: 00: No effect. If locked when the guidance is supposed to happen the guide music will play but Professor Oak won't move (nor can the player). 01: The valid behavior is responsible for Professor Oak guiding the player to his laboratory. Otherwise Fly away and freeze 02: If locked on Professor Oak guidance the guide music will play but Professor Oak won't move. Otherwise ACE (C43A) 03: If locked on Professor Oak guidance the guide music will play but Professor Oak won't move.

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 04: Freeze 05: Freeze

In Pokémon Yellow
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 08: VRAM execution (froze at unknown opcode at 8CFA) 09: ACE (FA47) 0A: Freeze 0B: Freeze 0C: Unknown/seemingly nothing happens 0D: Freeze (00 90 3E 80 corruption pattern) 0E: Freeze 0F: Locks up controls, hides NPC sprites, corrupts audio for a while, then freezes 10: Seems to corrupt the map blocks similar to 05 11: Freeze 12: Locks player, invisible text box with Start menu open, pressing A or B freezes the game, other buttons seemingly do nothing 13: Play raw audio (similar to Pikachu cry) then ACE (D7E1). If ret, still a freeze 14: Unknown/seemingly nothing happens 15: ACE (FA86) [*1] 16: Seems to corrupt map blocks like 05, 10 17: Seems to corrupt map blocks like 05, 10, 16 18: Freeze (00 90 3E 80 corruption pattern) 19: Freeze 1A: Freeze 1B: Seems to corrupt map blocks like 05, 10, 16, 17 1C: Freeze 1D: Freeze 1E: Freeze 1F: Freeze 20: Freeze 21: ACE (CD1C) 22: ACE (CD3E) 23: Freeze 24: Walking lag glitch 25: Freeze 26: ACE (F606) 27: ACE (CD3E) 28: Freeze 29: Walking lag glitch 2A: Freeze 2B: Unknown/seemingly nothing happens 2C: ACE (D731) 2D: ACE (F606) 2E: ACE (CD78) 2F: Unknown/seemingly nothing happens 30: Freeze 31: ACE (CC3D) 32: ACE (CF1A) 33: Freeze 34: ACE (E5C4) 35: Freeze 36: Unknown opcode 0xE4 at 33CD. If skipped seemingly nothing happens. 37: Freeze 38: ACE (FA22) 39: Freeze 3A: ACE (C0F0) 3B: Freeze 3C: ACE (EFEA) 3D: Freeze 3E: Lock up controls for a while, then display the message that the Safari Zone game is over. May proceed to run ACE (CD15). If ret, player steps down spinning and warps but loops down the screen seemingly infinitely 3F: Freeze 40: Freeze 41: ACE (F002) 42: ACE (EA7C) 43: See 3E 44: ACE (CDD0) 45: Unknown opcode 0xD3 at 284C. If skipped over (i.e. like on Virtual Console) may display invisible text box and Start menu, and freeze game if press A or B. 46: Freeze 47: Lock moving, invisible text box and Start menu, freeze game if press A or B. 48: Walking lag glitch 49: ACE (EA0C) 4A: Unknown/seemingly nothing happens 4B: Freeze 4C: ACE (F5D5) 4D: Freeze (3E D2 corruption pattern) 4E: Freeze 4F: Freeze 50: Freeze 51: Freeze 52: Invisible text box and Start menu, if press A or B, heavily corrupt screen and freeze game. 53: ACE (C8A7) 54: Freeze 55: ACE (F5D5) 56: Unknown/seemingly nothing happens 57: In Red's house 1F flower tiles appear on the benches. They don't animate. 58: Freeze 59: ACE (F5D5) 5A: Freeze 5B: See 57 5C: Freeze 5D: ACE (F5D5) 5E: ACE (C93E) 5F: Freeze 60: ACE (F5D5) 61: Freeze 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 71: Bring up invisible text box with Start menu open and lock moving. If press A, get invisible Yes/No prompt. All options (Yes, No, B press) may result in a freeze. Can reload the save file and seemingly nothing happens (if not corrupted) 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. 7A: Walking lag glitch and eventual freeze 7B: Invalid opcode 0xD3 at 0600. If skipped over, ACE (D1D1) but freeze. 7C: ACE (D211) 7D: Freeze 7E: Freeze 7F: Freeze 80: ACE (D0B4) 81-FF: Same as 01-FF? *1: In stored Pokémon data (Pokémon 6)
