This is a MelonLoader plugin for running UnityModManager UMM) mods under MelonLoader.

Changelog

• Cross-runtime type compatibility — IL-rewrite Creplay to change sortedKeyQueue_instance field type and all isinst PriorityQueue to object, bypassing CLR type identity checks; add NeedsMethodRedirect in ProxyPatch to redirect generic method patches to the game's actual instance
• Assembly loading strategy — Switch to LoadFrom via temp file to preserve load context, preventing generic type splitting; intercept Assembly-CSharp in AssemblyResolve to reuse already-loaded instances, avoiding duplicate loads
• Conflict migration — When a transpiler patch arrives at a method already claimed by ProxyPatch, non-transpiler patches on HarmonyX are automatically migrated to 0Harmony_UMM, allowing a single runtime to host all patches
• Three-layer resolution — UpdateWrapper IL injection (CreateClassProcessor path), Harmony.Patch() prefix (direct Patch path), ProxyPatch routing (Cecil rewrite) — no gap
• InvokeNativePatch extracted — Unified native entry point, fixing silent drop of non-transpiler patches due to load order
• MigratePatches exception safety — Caught in TryResolveConflict, routing fallback on failure, no crash
• Creplay message display — Patch TriggerMessage to show on-screen in top-left corner using unscaled time (unaffected by pause)
• Assembly.Read guard — Skip non-.NET assemblies with warning instead of BadImageFormatException
• Known limitation — Cross-runtime transpiler patches on the same method cannot coexist (CodeInstruction types belong to different assemblies)
• Compatible with JALib
