All gameplay that I've experienced.
What does not
The server MOTD (or where I assume there should be a MOTD when joining an online server) is completely blank (as in CS:S). You might get banned from a server for not following rules you cannot see. Luckily, the objectives and hints are on a separate screen - which does work.
Some textures have an over-white issue. When you're a zombie, you will see many bright white triangles on parts of your hands.
I haven't played the game on windows, but some textures also appear as if they might be showing up darker than intended.
What was not tested
Voice chat: It probably works to some degree, though there have been quality issues reported in other Source-based games.
I'm rating this as Gold due to the few issues, and the fact that you need to override the OS to Win98 for hl2.exe to avoid crashing.
