Summary
This data pack will turn Cobblemon into a relatively Gen 1 experience. No extra forms, no extra evolutions, only Gen 1 pokemon.
Ancient Pokéballs & Held Items remain unchanged, but can be easily modified within the data pack.
Known Incompatibilities
Riding
- Some rideable traits of some cobblemon are not fully implemented in Cobblemon and therefore not rideable with this datapack either.
- Once these are completed within Cobblemon, they will be added to the datapack as well.
- Reference Tickets
Cobbreeding
(As of March, 2025, untested in later versions)
- The mod seems to search for all pokemon during an egg spawn, but the gen1ify removes most, leading to a crash
Updating
For any patches/updates I make, just replace the datapack file in your world folder with the new one. For the mod, replacing the mod should work fine.
FAQ
Feel free to reach out to me (gabecurran) in the Cobblemon Discord for any questions!
