I think it might be useful to add a comment about game_exeW[0] == L'\\'.

I'm not a Windows dev, but I searched around and it seems leading backslash is supposed to translate to the root of the disk we're currently in.

That implies the line game_exeW[0] == L'\\' is working around BattleEye bug, where it translates the dir incorrectly (i.e. the game that works on Windows actually wasn't supposed to work there either).

So, I think it's useful to add a comment explaining the situation, i.e. why exactly we do the game_exeW[0] == L'\\' check here.
