I was wondering that if I was to put my own custom tracks onto GTA: Liberty City Stories, would I still be able to enable the radio banter too? Like commercials and the in game news updates?
You get to choose. With custom tracks enabled, each track acts as its own individual radio station. With radio enabled, you can just listen to the radio. I'm pretty sure the in-game news updates will still be audible either way, though.
you can't have commercials with custom tracks enabled, but i'm guessing the important announcements still pop up.
