* hle: Simplify ServiceNotImplementedException This removes the need to pass in whether the command is a Tipc command or a Hipc command to the exception constructor. * hle: Use the IPC Message type to determine command type This allows differentiating between Tipc and Hipc commands when invoking a handler that supports handling both Tipc and Hipc commands.
