Hi Geod,
First off, I just want to say how utterly game changing this is. Wow. I am blown away by not only your creativity to dream up such a concept in the first place, but then to go on and develop it so damn well. I am in awe of your talents. I sent you some money to support this project, and I can't wait to see where you take it, especially with the help of the community who are editing such stellar .3dn files. Thanks to everyone involved!
My main wishlist is that I would eventually love to see a version of the emulator ported to the Linux-based Raspberry Pi. Playing on my computer is fine, but I do most of my retro gaming on my TV. I've got the Pi running Retropie and Emulationstation, and my God I would LOVE to have 3DNES functional on that thing. Is this something you ever envision yourself working on to implement? Even if it's a premium feature, I would happily pay for a version like this.
Once again, thank you to everyone for being so damn awesome.
