This might sound like a really bad idea at first, but since many of these plug-n-play game systems are based on NOACs, shouldn't it be possible to add support for the games to a NES emulator via new mappers. That is, simply treat the games as if they were any other pirate multicart. I realize that NOACs are slightly different than a real NES, but then again, emulators support some multi-carts that come packed with Famiclones.
Commercial dev for the NES never stopped, if you consider NOAC dev to be NES dev.
