Some themes' BGMs dont load in the preview.

I noticed a couple of themes from theme plaza wont load the BGM in the preview of Anemone.

The themes are: https://themeplaza.art/item/46942 https://themeplaza.art/item/7884

When installed they work correctly.

Another issue is that BGM for themes downloaded from the old 3dsthem.es also dont load (maybe because it doesnt have the ogg file in the folder?). They used to work on themely.

RE: old 3dsthem.es theme previews: yes, the missing OGG is exactly why it doesn't load, we don't have a bcstm player in Anemone (Themely did, IIRC) - and we won't be adding one. With regards to those previews not working, someone can take a look, but I'm 70% sure on first look that it's a problem with the preview.ogg files.

The themes are using mono bgm.bcstm files, which is problematic for other reasons, but this leads to the bgm.ogg file also being mono. We don't currently handle the case where they're mono (preferring instead to assume that well-made themes will use stereo audio), but we can in theory.

As of 3.0.0 Anemone uses the bgm.bcstm for the preview and supports both mono and dual channel audio. Still do NOT use mono audio BGMs - the 3DS home menu does not properly support mono bcstms, and even though the preview plays fine in Anemone you will run into issues once you install the theme.
