It's about time that I get back in touch with you folks.
Sorry about my lack of support. As skipster said, I've been struggling with depression and have been in hospital for that. I know many people won't be interested in the details, but I feel like it's important to talk about those things. If you're not interested in that, feel free to skip the next paragraph.
Still reading? Cool
I'll try to keep this short anyways.
I have been in hospital in September and October because of severe depression. August was probably the worst month, I planed on committing suicide back then (I'm glad I didn't actually do that), but it started months earlier and lasted longer then the stay in the hospital. I'm slowly getting back on track, I started doing important tasks I didn't do while the depression was stronger and I'm finally starting to do the things I like again. I know, it doesn't sound intuitive that I start doing the things I like last, but that's just how it is for me.
During the bad time, my work on CDC and C3C was one of the first hobbies I stopped doing because it started to feel like work. Although I like creating this software, it's already good enough for my personal purpose and making it work for others is mostly just that: work. I needed to drop hobbies like that to recover.
Fortunately since late December I feel much better thanks to new medication. This means I can finally get back to CuteCapture and try to make it work for your use cases as well.
So, what does that mean? Will I release a new and shiny version of the software tomorrow, with all the features you ever wanted and all those you never dreamed of? Well, no. Sorry, I'm not that fast.
But it means I'll try to be active in this thread again, listen to your problems, try to help you fix them and work towards audio and mac support. I can't and won't give an ETA on that, that never really worked for me ^^"
About the new 3DS support: I can't really tell you something about that right now. I'd love to make that happen, but I don't currently own a new 3DS, especially not one with a capture unit. Ages ago Loopy mentioned that the new 3DS is a bit harder to initialize, I'd need to get in contact with him for that, but having no unit I could test my code with makes developing this hard. Unfortunately I can't currently afford a new 3DS with capture unit, so I guess this is won't happen in the near future, as much as I'd love to make it happen. Sorry!
