How would developing a game for Game Boy ™ with http://gbdk.sourceforge.net/ or https://github.com/rednex/rgbds count?
This would give OSKarma for the engine and creative commons assets when I use some.
But how do FLOSS emulators count, is it then created using an open platform, is it running on one? After all, I don’t think it’s more locked done than my Intel CPU.
