Direct law is fine. You may have been overweight and dual hyd fail, which will make life harder and the stall more likely due to the lack of flight controls maybe?
For the sim profile it's best to configure on a long straight final. Ask for it from ATC. Also use manual thr and don't take all the power off when you start to configure and when you do don't stop until you're at flap 2. It's G+B hyd that has failed so on selection of flap 1 you don't get anything until you select flaps2. Slats are inop. It's probably why you got the stall warner.
As a tip i've found configuring in a shallow descent makes it easier. If the VSW starts to increase towards KIAS you can gently unload the wing to control it.
anyway just my 2 bobs worth
