The current extension is about to be 10 years old and lacks the latest SDK features, and seems that both CT & author are too busy and don't have time to update it.
However, it indeed covers more than 80% SDK features, so it's a lot of unnecessary work to rewrite it. The aim is, make an extension as the complement, add features like detect remote play device types / User language, and the original one remains untouched.
So, I'm here to gather wanted features.
New version modified lib file so it will load latest dll in another file name, in theory it should be compatible with old one.
You need to create steam_appid.txt according to the valve's document, and make sure the ID in this file is the same as the one in the old ext's properties. Different ID may conflict due to the initialize order, maybe overwrote.
Note that this work won't be fast, depending on the development state of my game, and the features I need will be added as the highest priority.
