GRAPHICS MOD NOTE
With NaturalVision Evolved (NVE) installed, Nitro exhaust flames may appear blue or cyan depending on the selected visual setup.
This is a visual difference caused by NVE and does not affect N.O.S. functionality.

AUDIO NOTE
The Nitro sound uses source audio from Need for Speed: Underground 2.
I recreated and mixed the final Nitro sequence manually by ear, so it is not intended to be a 100% exact reproduction of the original NFSU2 sound mix.

PUBLIC API / MOD INTEGRATION
N.O.S. includes a small public API that allows other mods to read Nitro state and react to N.O.S. events without accessing its internal physics or gameplay systems.

The API is intended for HUDs, speedometers, machinima tools and other optional integrations. Developer documentation and a basic integration example are included in the archive.

For detailed API, compatibility or integration discussions, you can contact me on Discord. My Discord server is linked in my GTA5-Mods profile.

LEGACY SPEEDOMETER INTEGRATION
The Legacy version includes built-in support for Need for Speed Underground 2 Speedometer.
When the integration is enabled, its N2O gauge can display the current N.O.S. charge.

The speedometer itself is not included with N.O.S.
