Originally for GTA1, this program now lets you listen to (and change) all the sounds from GTA2 as well. Great for livening up those boring Windows sounds :-)
The most recent version of the game's audio file editor, released in 2002. Suitable for GTA 1 and GTA 2. It allows you to listen to sounds, effects and phrases, change the frequency and sound itself, delete, save in wav format, backup and restore.
Installation:
The archive contains the program installer. Run it and follow the instructions.
In the installed program, in the "options" tab, specify the paths to the audio files and launchers of GTA 1 and GTA 2. Then you can use the program.
