poketransform is a project which follows the story of a Ditto dropped off at the daycare on Route 117 in the Hoenn region, tasked with obtaining an Egg. The thing is... no one, not even the Daycare Man, knows where Eggs come from. Additionally, Pokemon in the daycare seem quite confused about how they are supposed to be gaining EXP. You will to follow the journey of Ditto as it learns the secrets behind where Pokemon Eggs come from and how EXP is gained in the daycare.

You can patch your legally obtained copy of Emerald directly on the poketransform patching site.
Alternatively, you can download the zip file containing the patch file in the Releases section here.
The zip file contains:
- A patch file for poketransform, to be applied to Emerald
- A copy of this ReadME file
You can download boxart from right here in the repo!
Here is the current one I am showcasing, credit to Kurizo on discord:
Use Rom Patcher JS to patch the files. You will need to provide your own legally obtained copy of Emerald.
- Upload the Emerald.gba file to the "ROM file" section
- Upload the poketransform patch file to the "Patch file" section
- Look for a green checkmark and hit apply patch.
This will automatically download your new poketransform.gba ROM for you to play!
