Can I configure the analog stick on my PS3 controller as "vehicle throttle" in GTA3 on Mac?

I bought GTA3 on Mac App Store, and wanted to play it with my new PS3 controller on my MacBook. It works fine for playing on foot (left stick for running, right stick for view). But in car I can only use left stick for steering, and can't use analog stick for throttle.

I tried to redefine the controls on car, but when move the sticks they are not recognized in the "redefine controls" menu, only buttons are recognized.

How can I make so that I can control throttle with analog stick?

UPD. Actually I cant reassign analog sticks at all, not even change steering from left to right stick, they are simply not recognized, and I can play only on default settings for sticks.

UPD2. What about GTA SA, then? Will I be able to to control both throttle and steering with analog sticks in it?

Solution 1:

The original version of GTA3 used a button, and not a analog stick axis, for both throttle and brake. On the other hand, the DualShock 2 had pressure sensitive button support, so on the PS2 they were more like analog controls than digital buttons.

However, most of the ports of GTA3 don't support analog throttle/brake for whatever reason. It might be possible to use a controller remapping program (AutoHotKey is my go-to for this, but I think Controllermate might fill a similar niche in OSX) in order to change this behavior. However, it's likely to break other things you'd want to do with the right analog stick - like looking around when you're on foot, for example.

I think in the end you might just have to chalk this up to a missing feature in the ports of GTA games.
