- Fixes Winnie the Pooh wind sounds, bug #14454 - Fixes Donald Duck's Playground sound 5 - Fixes various sounds in KQ2 and BC The sound loading code attempted to detect AGIv1 sounds by the first two bytes, but this dind't work beause AGIv1 sounds have no header. Each AGIv1 game has at least one sound that failed this heuristic. Now we use the interpreter version instead of attempting detection, which is what the sound playback code in SoundGenPCJr does anyway.
