Pokemon Blue US Gameboy Game Genie Code - Always Catch Pokemon

[Feelber]

I wanted to share this code, but I'm also hoping someone can help improve it if possible. I found this using bgb on Pokemon Blue.

Always catch Pokemon successfully:
01431ED1

Address: D11E
Value 43

Caveat: Code must be turned off when not in use because it will freeze the game if another action, like attack, is used.

Help Wanted

Rather than relying on the internal RAM value at D11E I would like to locate the opcode that determines whether an attempt catch will be successful or not. I recommend setting an access breakpoint at D11E and throwing a pokeball a few times. You will notice a sort of fork in the code that is run for successful catches vs failed catches. I'm trying to narrow it down to the precise opcode address so that it always jumps to the success sequence. Unfortunately, I'm not sure it is possible due to many opcodes serving multiple functions in the game.

Yes, I realize one could simply use a code for unlimited master balls, but for a game that's been around this long, this seems like a code that should exist by now and it's a fun challenge to find new codes. If you don't get it then this post is not for you.

Let me know if you find anything. If not, enjoy using
the code as is.

I have located the table for the catch rates per each Pokeball type. I also made a code with a 100 percent success rate 008-21A-C4A but it won't actually throw the ball.

1.??8-31A-A2A
2.??8-39A-6EA
3.??8-41A-6EF
4.??8-41A-6EF
5.??8-51A-6E7

Its late when I did this and I'm tired, so I only did the bare minimum.

So what values go in ??

So, the following two codes will guarantee 100 percent success rate of capture

437-FCA-6E3
437-F6A-6EF

Here is the rundown:
61 is the value of a Pokemon that is going to break free
62 is the value of a Pokemon that appeared to be caught
A5 is the value of a successful capture.

Pokemon Yellow.gbc does things exactly the same except that the address is one byte lower (D11D) instead for some reason.

The following two codes will guarantee 100 percent success rate of capture

435-8AA-6EF
435-92A-6E3

Here is the rundown:
61 is the value of a Pokemon that is going to break free
62 is the value of a Pokemon that appeared to be caught
A5 is the value of a successful capture.

For those who feel like experimenting, ??3-E5A-E67 will modify the successful catch action, or what happens instead of catching a Pokemon.

PokemonMidori does things exactly the same except that the address is one byte lower (D0E3) instead for some reason.

The following two codes will guarantee 100 percent success rate of capture

438-66A-6EF
438-6CA-6E3

Here is the rundown:
61 is the value of a Pokemon that is going to break free
62 is the value of a Pokemon that appeared to be caught
A5 is the value of a successful capture.

For those who feel like experimenting, ??7-29A-E67 will modify the successful catch action, or what happens instead of catching a Pokemon.

This should also work with the other Japanese versions but that hasn't been tested yet.
