I uploaded an update to fix the non playing file in march of 1942. I also added one radio tokyo file announcing the surrender of Singapore in feb 1942 (japanese language audio). If anyone has any sources for japanese language audio, please share as radio tokyo is terribly inadequate as it is.
Install with JSGME or just drop the files in the correct folder from \data\sound\radio.
