Question about a selection in EPSXE 1.7.0

Hmm, when I go into config > Gamepad > port 1 > pad 1and select Digital/MouseDoes that mean I can use the mouse to aim? Like I would with a dualshock controller, I'm asking this because I really want to play Armored Core MoA but I don't have a gamepad to aim.

Since no one wants to answer, I'll try it myself.
*goes to possibly waste 286 points on AC MoA*
