About this Mod
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.
