Sword & Shield (v1.1.0) | Live RAM Encounter Edits

[AliceTheAlice]

Hello all,

For those who do not know me, I studied under a video game development program in the early 2000's. While I did not end up pursuing development as a career, I still actively apply the knowledge to trying to understand what's under the hood of the franchise that first made me want to go into video game development: Pokémon.

The Atmosphere CFW OS for CFW uses a built-in cheat app called Edizon which means every single CFW Switch owner with Atmosphere OS are forced to use it. The homebrew app Edizon does not allow for a manual ON/OFF of individual codes which means people interested in experimenting have to maintain their own database of codes and go through the hassle of deleting and re-adding codes to the .TXT file for the codes for the game on a FREQUENT basis.

I would like to premise this thread with the following: I am not a code hunter. I simply want to share the compiled database of codes with insight so that the community can continue to better its understanding of the game's internal mechanics.

 

Game	TitleID	BuildID (for v1.1.0)
Pokémon Shield	01008db008c2c000	bdd027f80fab4ef4
Pokémon Sword	0100abf008968000	490648316cc1ccdc

The result of these codes being hunted has allowed us to establish that there is ONLY a single module in the game which is used to determine all the random values for encountered Pokémon. For each of the individual variables which make up a Pokémon (in lamens: each of the individual fields you see in PKHeX), the module passes the data known/pre-determined elements to their respective space in MEMORY and for any blanks/missing elements those are calculated and stored into their respective space in MEMORY.

The module does NOT know when Live RAM Encounter Edits (cheats) are active and as such will not attempt to correct any mistakes. For example: applying a Gender to a Genderless Pokémon. Sword & Shield makes it abondantly clear when huge mistakes are made but replacing the 2D sprite with a black PokéBall symbol.

The module is used for all NPC Pokémon, Wild Pokémon, in-game gift Pokémon (including Fossil), and Eggs (obviously at time of receiving the egg.) This same module is used for Mystery Gift Pokémon as they are being received. Finally, this same module is used for all non-player Pokémon: both the NPC's Pokémon when less than four humans as well as the Raid Pokémon itself. (Note: due to checks between turns if any of the Pokémon in the Raid become abondantly illegal the Raid will crash 100% for the non-host and most of the time for the host.)

Live RAM Encounter Edits (cheats) both can create LEGAL and ILLEGAL Pokémon. The use of Live RAM Encounter Edits (cheats) serves to bypass randomization to reduce the number of times you need to encounter the same Pokémon to get the desired result. It's the "whole infinite monkeys with typewriters" factor: with enough time you would get the desired result so this allows you to jump to that desired result. However, it's only the game breaking Live RAM Encounter Edits (cheats) which are highlighted a black PokéBall symbol. The game doesn't know which Hidden Abilities are LEGAL and which ones are ILLEGAL.
