Hacking Pokémon XY/ORAS – Play with Pokémon at Their Real Sizes

[Zetta_D]

Hello, I recently showed a code in the Sango plugin thread.
I was asked to share the code so that it would be easier to distribute, so I made it in AR version, which is below.
Additionally, I’m including a commented C version of the code to help you understand it, or in case you want to adapt it for earlier versions. This was made on Pokémon Alpha Sapphire 1.4.
Here are a few demos (btw, Wailord is way too big to be displayed at its real size x'D).
I hope this will be useful for ROM hacks as well, like the No Outlines code.
I’ve only tested this on Citra, so if you encounter any bugs, please let me know.

nice. cant wait to see my wailord next to a skitty

Can OR also be used?

I don't have the game, but you can always try x)

Playing Sinking Sapphire. The game crashes when I load it.

Have you installed update 1.4?
Or does the ROM hack run on version 1.0? I don't know x')

 

[Peanucomp]

Can this be done for Ultra sun and Ultra Moon that have a bigger roster of Pokemon? that would be great

 

[Vezix]

Does this work in actual hardware?

Yes, the .text section, land & heap memory are the same on old/new 3DS/2DS hardware and Citra.

Yes, I described how the algorithm works above. All you need to do is find the addresses for the correct version of the game in question and apply it. I could take care of that when I have more time.

I dont know how to do anything like that, but Ill try and if I manage to make it work ill share it here, thanks for asnwering and for the code!

 

[Peanucomp]

Months later I did in fact not manage to make this happen lol

 

[Zetta_D]

I haven't checked it out yet either, sorry x'D - I'm focused on the Pokémon ORAS plugin.

Np take your time.

Im playing Rutile Ruby V1.4 (on 3Ds not emu) and tried this code and it crash the game, I wonder if it is because this was made for Sapphire, only works on citra or its a hack rom

Send me a memory dump while you’re in battle (use CTRPF → Gateway RAM Dumps), and I’ll be able to tell you where the error comes from x)

ORAS Rutile Gateway RAM Dumps
Luma Crash Dump
Drive Folder

Here you go, I tried other cheats like the No Outline one and it works fine, but I get a crash once I press R with your Size Code.

 

[Zetta_D]

I checked, and the memory is identical. However, your dump shows the crash occurring at address 0x0702DB48, which falls within the CTRPF memory range. It seems like CTRPF is what’s causing the crash.
I tested it on Citra, and it works fine with both the built-in cheat menu and CTRPF.
Try it with Luma3DS idk x)

 

[Peanucomp]

Oh well I guess ill wait to eventually use the cheat, for some reason USUM plays perfect on my PC with Citra/Azahar but Oras and XY are glitchy, hence why I installed Rutile on my 3ds. Ill way until someone ports this to USUM I guess, thanks so much for trying to help I know you are busy.

Edit: Tried it with regular Omega Ruby V1.4 and also the games freezes when I press R in the overworld, in both Citra and Azahar on PC and Android, im cooked I guess.
