I'm new here & thank to the first message, I'm now listen to the song that I've added in the save file. I'm going to tell you the easier/easiest way/s to check the song by:
Go to Start > All Programs > Accessories > Entertainment > Sound Recorder > File > Open, in this window you'll have to change "Sounds(*.wav)" to "All files(*.*)" and choose the .GTA file to listen, and next time Sound Recorder will appear in your Start menu...
If ^ too hard then try this:
Right click on a .GTA file > Open With... > Browse... > My Computer > Local Disk(C: ) > WINDOWS > systen32 > sndrec32 > Open, Tick in "[ ]Always use the selected program to open this kind of file" and click OK. Now you just double click or press Enter on a .GTA file to add the name of the song...
I hopefully this message will helps you guys/gals... Ask me if there are anyproblem or miss understanding.
