Hi guys, did you check recently? Using it for remote play is also why I'd buy this extension...
One of the recent Steamworks SDK versions added a few functions to fetch remote players’ inputs separately, but still they do not simulate Raw Input.
I’ve been working on an extension that automatically wraps majority of Steamworks SDK functions so that calling something esoteric like this doesn’t require messing with C++ - send me an email (and include your GM / Steamworks SDK version numbers) and I’ll get you a copy of it so far.
