DIY NES in a NES-ted cartridge

OK, so I couldn’t help myself with the “nested” pun in the title, but it does make plenty of sense (to me, at least). The wonders of miniaturization has brought us to this crossroads, where the old school Nintendo Entertainment System (NES) console has been shrunk into the physical size of an NES game cartridge. Yes, you read that right – a DIY enthusiast actually went through the trouble of fitting the whole classic NES console into an equally old school NES game cartridge, ports for controllers and all, including an on-off switch that is located within. Of course, this isn’t a factory inspired job, but a labor of love in the comforts of home. Anyone who wants a smaller NES console which is nigh portable can always look to the GBA SP (which is now defunct) – now that’s tiny. Anyone willing to give this project a go?
