I don't have a github account, so if someone could pass on. Win32ss needs a bcryptprimitives function, specifically ProcessPrng. Supermium doesn't have VMP anyway, so the author can change the import to his own implementation of bcryptprimitives in the patcher anyway. GetProcessMitigationPolicy and SetThreadInformation are also needed, but from what I've seen the author of Supermium certainly knows.

The world does not end with Netflix, there are many sites that use DRM, for which unnecessary for the author to buy VMP license for Supermium.
