YapiPaleofusion — Prehistoric Integration Framework
YapiPaleofusion is a compatibility and integration framework built around Unusual Prehistory (UP) as the central progression system.
Its purpose is to make several prehistoric-themed mods feel more connected by adding UP-style DNA support, compatibility recipes, incubation paths, item tags, spawn handling, and targeted gameplay adjustments where needed.
Rather than fully rewriting every supported mod, YapiPaleofusion focuses on selected integration points that improve cohesion, reduce conflicts, and make mixed-mod progression feel more natural.
The current release includes integration work for:
- Unusual Prehistory (UP) — Core System
- Prehistoric Fauna (PF)
- Shineal’s Prehistoric Expansion (SPE)
- Raxiores Of Raxiore (ROR)
- The Dawn Era (TDE)
- Unearthed Journey (UJ)
What This Mod Currently Does
• Adds UP DNA flask / analyzer / cultivator integration for selected creatures from supported mods
• Adds compatibility content such as eggs, roe, embryos, recipes, trades, and item tags
• Reworks or disables specific conflicting systems where needed, including selected spawns, worldgen hooks, portals, dimensions, and duplicate progression paths
• Improves cross-mod stability by patching or replacing problematic interactions between supported mods
• Loads integration content conditionally, depending on which supported mods are installed
YapiPaleofusion is meant to make a mixed prehistoric mod setup feel more coherent, while still respecting the identity of the original mods.
It is not a total overhaul of every supported mod, and integration coverage may vary depending on the mod and the specific creature or feature.
