I'd rather not make an entire thread about this, so I figure, I will just ask here and hope someone out there in the aether can answer me.
I'm currently working on developing a custom theme for my 3DS Home Menu, and I want to convert a song into a BCSTM for the background audio. I can't find any concrete information, it seems to me, on what specific requirements I need to meet for the audio track (as most of it seems to conflict with one another), or what good software to use to convert it, for that matter. I'm hoping someone can tell me without me having to join a Discord server or anything just to get the proper feedback I need.
So, what are the hard requirements for the audio for a custom 3DS Home Menu theme's background music? And what software do I use, with proper settings included?
