Im looking at halflife echoes, it has a crossplatform patch with this comment:You won't be able to play any mods that have custom game code (cl_dlls and dlls in the mod folder) unless that code is ported properly and supplied as an additional NRO.
Though I don't remember whether Crack-Life has custom code or not.
"NOTE: This version based on modified Spirit of Half-Life 1.2 without some features which was introduced in Spirit of Half-Life 1.5 and not required anymore cg.dll and cggl.dll libraries."
short of having an nro file, this could work on the switch?
