thx

You have to press L (or whatever activation key you're using for the shiny code) almost immediately after you press yes on the starter you want to select.

Thanx, that did the trick! Someone should make a cheat that just makes all 3 starters shiny by default, cause that hold L cheat loves to lock up the system if you don't time it right. lol

It's just the scripting on the starter encounter that the shiny code seems to not get along with. Everywhere else seems to be unaffected.

@ThePerplexedOne Would you be able to explain what first 5 lines of the activation code are doing?
I've started learning how to make ASM codes and I don't think I'm understanding your code correctly. To me it looks like you're writing over a debug line drawing subroutine with some instructions (that I can't figure out what they do). So I'm just wondering if I'm entirely out of the ball park on this, since I just don't know.

Has a code for 999x battle points and 999x mysterious shards been uploaded and/or created yet?

Pkhex is able to do both of those functions.

It's my code cave. Essentially, I am writing my own functions in "empty space" in the binary (first 5 lines) and calling it from the existing function. (final line)

The empty space will typically just be a bunch of nops and returns, so I'm free to write whatever I want in there.

Can we have a x2 and x3 versions for this? Thanks!

Okay cool, I'm glad I was understanding that you were writing you're own instructions.
If you don't mind, would you be able to explain what the instructions were that you put in the "code cave"?
I see you're altering the instruction so that it alters how HpMinus runs when it's branched to, but I don't know how to work back from you're hex codes to understand the instructions yet.

Also thank you for explaining, It's very much appreciated. I haven't come across many specific examples to learn from for BDSP.

Okay so let's take a look at our code and what that translates to in ARM:

ldrb w1, [x0, #0x3e] // Loads the value of x0 (as a byte) (first parameter passed) + offset 0x3e (which is m_friendship in BTL_POKEPARAM) into w1
cbz w1, #0xc // Checks if this value is 0, if it isn't, it will execute the next instruction, otherwise skip it.
mov w21, #0 // Loads the value 0 into w21
mov w1, w21 // Puts value of w21 back into w1 (this is the original instruction that we're overwriting in the final line)
b #0xffffffffff68ade8 // Go back to our original instruction, but the instruction after it (so we ain't looping)
b #0x975230 // This just brings us to our function

The first 5 lines are our function, and again, the final line is what takes us there.

Basically, what we're doing is checking if the pokemon being attacked has 0 friendship (it seems to me that all wild pokemon/trainer pokemon have 0 friendship), so if they do, they take damage, and we don't. The only case this may fail is if your pokemon has 0 friendship, e.g. you JUST caught it and it's your first battle with it.

To translate to and from HEX/ARM, you can use this: https://armconverter.com/

Also, it's worth noting that the bytes in our instructions in the code need to be reversed so that we can translate it.

E.g. the instruction `52800042` will become `42008052`. Don't just reverse it completely, only each byte block.

Thank you so much, that was perfect ♥
That helps out so much. Also thank you for the reverse reminder, I sometimes find myself trying out codes, only to realise the big endian button isn't toggled on armconverter

I picked up some things I didn't know I could do with IDA before. Very useful

Are the button activated codes working for you on ryujinx?

The way the code works is it sets the value to 99, however, with emulators having the codes permanently activated from launch, it means it's always setting it to 99, so for emulators you can't, since you have to restart to make changes to what cheats are active (as far as I'm aware, granted I've not used the emus, just been reading other peoples posts).

That's true, but the code you provided with the button activation works like a charm. I get 99 with my first encounter and the chain count keeps on going up to 100+, which is what I was looking for. And once I'm done with that chain, I press R to restart the chain count and now I can encounter a new pokemon and start a new chain with no issue at all. Perfectly done, thank you.

 

[awesomelink234]

How do I use the radar chain codes? I saw one on CheatSlips that said to hold L, but I set the code to only do 40, and it doesn't work no matter where I hold L.

Can someone tell me what do the GBA cheat codes do?

It acts like the original game. When a gba cartrige of a pokemon game is inserted in slot 2, you get newer pokemons that you couldn't encounter in the wild

I don't think these pokemon are legal for online since there's no way of inserting a gba cartridge to the switch

PKHeX will flag them as illegal, but I don't think they will have any issues with online trading or battling (as long as they aren't further modified) since Nintendo's legality checks are far more lenient than PKHeX's.

For the most part it's better to get them in the Underground, though, where they can be obtained at higher levels and with egg moves to boot.

So I noticed the main cheat file was last updated in november, is the person that started this even around anymore? and if so, why's it not been updated? XD

She was recently in an accident and is currently recovering, so things are a little slower here in terms of updates (She's is also a prominent in the ACNH cheat & reverse engineering scene, so spend time there as well).
