How to play GTA IV using your generic controller

How to play GTA IV using your generic controller
A guide : Works with all controllers (tested by me) INFORMATION: This extremely simple guide will teach you how to emulate an xbox360 controller, because IV supports only that. Now, you can use any controller you wish (unsure about wheel and pedals).
1) Download the following archive.
2) Unpack the xinput9_1_0.dll and the xbox360cemu.ini from the archive into your gta4 dir.
3) Edit the .ini according to your personal controller, or however you may please. The .ini is initially set up to work 100% correctly with Logitech RumblePad 2 and my ps3 controller. Note: in order to understand how to edit key mappings, read the included readme.txt. To configure the DLL, you'll have to stick a file called xbox360cemu.ini into the C:\Windows directory. See the sample INI for an example setup. The INI file itself is pretty simple, you have a section [PAD1], underneath you have the key=value mappings. The possible keys fall into a few categories, each with differently interpreted values. The buttons simply have a positive integer assigned to them, indicating the index of the mapped button (starting from 1). The keys for the buttons are: A, B, X, Y, Left Shoulder, Right Shoulder, Back, Start, Left Thumb, Right Thumb, D-pad Up, D-pad Down, D-pad Left, D-pad Right Analog sticks each have an axis assigned, again starting from 1. If you want to invert a particular axis, use negative indexes. The keys for the analogs are: Left Analog X, Left Analog Y, Right Analog X, Right Analog Y Triggers can be assigned to a button, axis, or slider. If the first character of the value is 'a', it refers to an axis, if it is an 's' it's a slider, otherwise it's a button. The rest is the index, which is used the same way as in the previous two cases. The keys for the triggers are: Left Trigger, Right Trigger The last key is "D-pad POV", if you give it a value (starting from 1), the POV/hat-switch with that index will be assigned to the D-pad.
