Thanks for your feedback on PocketFab! You're right about the design of the physical devices being as much a part of the experience of playing these games as the gameplay itself. For that, I think RetroFab will still be the best way to experience these games.
Thanks for the reply. After I wrote my initial post I was hoping that it didn't come across as offensive as it was meant to be constructive but I think you understood that. Greatly appreciate all your efforts and continue to be amazed by what you have achieved, especially as you are just a sole developer, I'm in awe of developers such as yourself.
