The 100% catch cheat doesn't seem to work in 1.1.1, unless it doesn't affect raids?
In addition to the capture formula when dealing with Wild in the grass Pokemon, Raid battles check the game for 3 factors which will further modify your chance to capture a Pokemon. The capture codes for Red & Blue via the GameShark right up to CFW in Sword & Shield have ALL been the exact same memory manipulation:
The codes set the capture percentitle roll to 100%.
(When you see the ball shake, the game is rolling a percentage value akin to rolling a 100-sided dice for tabletop RPGs. As long as you roll above a value determined by math based upon the species, it's current HP, and if it's got a status condition which if the game rolls above it moves to the next shake. The codes set said shake rolls to 100%. Which means using the Beast Ball with 10% success rate means, rolling that 100% means you only have 10% it was successful... essentially.)
In Raids, the Pokemon's species catch rate is reduce to that of a Legendary Pokemon if it is a GMax. In addition, there's a check which determines if the Raid is in-game or one of the Promoted ones. If the Raid is in-game AND is not Promoted, the ENTIRE Capture Rate formula is bypassed and you JUST catch the Pokemon.
The only way for a Code to provide perfect Capture in Raid battles is to trick the game into thinking you are in an in-game, non-Promoted Raid (which might internally issue the mon with an illegal ID if you were not the Raid host since that internal ID is based upon the host's save file) OR the code tells the game when looking up the PokeBall that it is a Master Ball (which might change the ball type.)
These are code patches codes, so to find / update them you need ida pro, but most of them are almost the same as 1.1.0, just a +0x40 difference...

I have never seen an Instakill that worked past the Base v1.0.0 of the game. The original code worked in Raid Battles. So, if this works... yippie!
