Headset Radio (+mp3 player) v2.1
Read this description carefully to understand how to make everything work the right way !!! Read it to the end !!!

Collab with @ArtemQa146 and @KaiQ
Thanks for everything !

This mod adds an MP3 player that looks like headset radio.
The model was made by KaiQ based on real radio headset from early 1990s.

MP3 player works when player is on foot, on a bicycle, in/on any vehicle.
Besides, you can enable standard in-game radio on bicycles and police vehicles (all vehicles without radio, actually).

Installation:
MP3 folder - to game's root folder (ex. \GTA San Andreas\MP3\)
HeadSetRadio - to modloader folder

Functions and controls (you can change them in .ini):
R+M - enable mp3 player
R+N - enable radio
You can also change modes with these keys.
In-game radio does not work when player is on foot!!!

The rest of the keys are mapped to numeric keyboard (can also be changed in .ini)
R+7 - track back
R+9 - track forward
R+1 - folder back
R+3 - folder forward
R+8 - pause
R+(+) - volume up
R+(-) - volume down
R+(*) - enable random mode

2 random modes. Set the mode in .ini
1. Picks a random mp3 file from any folder in \MP3.
2. Picks a random file from the folder that is currently playing.
Random mode is activaded by R+* (on numeric keyboard). Change it in ini if you want.
Jump to next random track by pressing any control key (Next/prev track, next/pref folder).

IMPORTANT!!!
There should be no loose files in your MP3\xxx subfolders. Only mp3 files, nfo.txt and fld_hsr.dat.
DO NOT delete or alter fld_hsr.dat files, wherever they are. It will mess things up.
DO NOT create empty subfolders in MP3\
DO NOT copy mp3 files to MP3\. Only to MP3\subfolder\

In your subfolders you can create text files "nfo.txt" with
these two lines:
[Name]
Name=Radio FM 1

When you will switch to this folder - the name will be displayed in game, like standard radio station name.

Mod comes with example MP3 folder, so it would be easier to understand how's it organized.
