Yapi: Paleofusion

Yapi: Paleofusion sits between mods that each add dinosaurs and prehistoric creatures and the central progression system of Unusual Prehistory. It adds DNA support to the supported mods, so DNA, flasks, analyzers, cultivators, eggs, roe, embryos, recipes, trades and spawns follow one shared path. Compatibility recipes, incubation paths, item tags and spawn handling are adjusted at selected integration points, and some conflicting systems are disabled where needed, including certain spawns, worldgen hooks, portals and dimensions that would otherwise duplicate progression paths.

The integration content loads conditionally, so only the supported mods that are installed are touched. Cross-mod stability is improved by patching problematic interactions between them, and the coverage differs from mod to mod depending on the creatures and features each one adds. The layer works alongside Unusual Prehistory and is not a rewrite of the supported mods, which keep their own identity. Forge is the only loader, and either side can run it while neither needs it. Files cover 1.20.1 only, and the code is under the MIT License but is not open source.
