Game mashup by passthrough

Start-up checklist for "make game A show game B's stuff", from a project that reached a working in-game lab build. The settled technical results (offsets, UE4SS fixes, retargeting, HUD split) live in project-intel/references/game-mashup-melty.md: load that card next. Engine routes and per-game recon come from universal-modder (mashup-mods guide). This skill is the order of work and the guardrails; it does not select Melty or any publishing platform (publishing is a separate, explicit request).

Pick the route (a wrong pick costs days)
