These days, it’s possible to get a single-board computer the size of a stick of gum. This will give you the power to emulate thousands of games and you can run one off batteries inside a handheld of your own devising. [Redherring32] took an altogether more creative and old-school approach with the TinyTendo, however. This is one pocket-sized NES that actually runs on genuine hardware. (Nitter)
The feat was achieved by drastically reducing the size of the original NES hardware to make it fit into a Game Boy style form factor. Key to this work was creating a custom cut-sized motherboard which uses original Nintendo DIP chips that have been machined down to become more like QFN-style surface mount packages. With that done, the chips can be assembled onto the TinyTendo PCB which is even smaller than a contemporary Raspberry Pi 3. It’s all assembled in a custom case, with USB C for charging and a bright and colorful LCD screen.
The TinyTendo is designed to use mini-cartridges created by [Bucket Mouse], a hacker who’s no stranger to impressive custom Game Boy hardware. By virtue of running genuine NES hardware, there’s also the possibility that the TinyTendo could play full-sized NES carts with a simple adapter.
This project has been a long time in the making; we first looked at [Redherring32]’s efforts back in 2021. It begs the question why the original NES was so big when Nintendo clearly had plenty of space to spare in those hefty DIP packages! ..
