Adaptive triggers, directional rumble and a siren lightbar, driven from your game's own weapon data. DSX not required.
Each weapon gets its own adaptive trigger, gunfire is felt on the side it came from, and the lightbar turns into a police siren when you are wanted. It reads your own weapon data, so the feel follows the guns you have.
Nothing is requested from YouTube until you press play. Watch it on YouTube instead.
GTA IV shipped for a pad with two rumble motors and no lights. Everything here comes from reading the game's live state and writing straight to the controller.
Pistols click once a shot, submachine guns rattle, the AK-47 thumps slower and harder, and the minigun grinds. All of it is worked out from the fire rate and magazine size in your own weapon files, not a hardcoded list.
The two motors are driven separately, so a shot from your left is felt on the left. In a car the right trigger starts weightless and grows heavier the further you press.
Scoped, GTA IV ties looking and walking to the same stick, so moving drags your aim with it. The mod holds the camera steady while you strafe, and the right stick looks while the left strafes and zooms.
Your lightbar colour is left alone until the police want you. Then it alternates blue and red, faster at higher stars, and hands the colour back when you lose them.
Press F7, or Create and Options together on the pad, for every trigger, rumble cue and light. Changes apply instantly and save themselves.
The zip mirrors your game folder, so dragging it in puts each file where it belongs. Only the driver needs a real install.
ScriptHookDotNet.asi in your GTA IV folder. It is not in this zip: it is a
separate project on its own licence, and it has to match your game build.GTAIV.exe, next to common, pc, TLAD and TBoGT.scripts, the script host files in the root. Choose merge if Windows asks._optional\ViGEmBus driver\ViGEmBus_Setup.exe. Skip it if you already use DSX or DS4Windows, which install it too.
Match the script hook to your game. The Complete Edition on Steam is 1.2.0.59, which
v1.7.1.8
is built for; 1.2.0.43 needs its own build. The wrong one loads no scripts at all and says so in
ScriptHookDotNet.log — check yours in GTAIV.exe, Properties, Details.
You also need an ASI loader. FusionFix includes one; otherwise install Ultimate ASI
Loader, the 32-bit build. Never run two at once, such as an old dsound.dll beside
FusionFix's dinput8.dll.
Close DSX before playing. It hides the pad from other programs. To keep DSX running, set the backend to Dsx, which keeps the triggers but drops the directional rumble.
Change any weapon below and its line appears on the right. Copy that into scripts\DualSenseIV.weapons.ini, then pick Reload weapon config file in the F7 menu.
| Field | Range | Meaning |
|---|---|---|
| click | — | Resistance that gives way with a snap, once per shot. Pistols, shotguns, snipers. |
| rattle | — | Shakes the trigger while you hold it down. Submachine guns, rifles, machine guns. |
| bow | — | A long pull that builds tension and releases. Rocket and grenade launchers. |
| grind | — | Spins under your finger before firing, then rattles. The minigun. |
| resist | — | Plain constant resistance, no click. Thrown weapons. |
| none | — | Free trigger, no effect at all. |
| strength | 1 – 8 | How hard it pushes back. One is a feather, eight is as stiff as the pad goes. |
| rate | 1 – 40 Hz | Shakes per second, used by rattle and grind only. Roughly matches the gun's real fire rate. |
| start | 0 – 9 | How far down the pull the effect begins. Zero is the very top, nine is the bottom. |
Leave a field out and the mod keeps its own value, so 34 = strength:4 lightens the Advanced
MG and nothing else. Delete the file to reset every weapon.
