C64 on desk with NFC TeensyROM and game token

TeensyROM NFC Game Loading On The C64

May 23, 2025 by Heidi Ulrich 6 Comments

When retro computing nostalgia meets modern wireless wizardry, you get a near-magical tap-to-load experience. It’ll turn your Commodore 64 into a console-like system, complete with physical game cards. Inspired by TapTo for MiSTer, this latest hack brings NFC magic to real hardware using the TeensyROM. It’s been out there for a while, but it might not have caught your attention as of yet. Developed by [Sensorium] and showcased by YouTuber [StatMat], this project is a tactile, techie love letter to the past.

At the heart of it is the TeensyROM cartridge, which – thanks to some clever firmware modding – now supports reading NFC tags. These are writable NTag215 cards storing the path to game files on the Teensy’s SD card. Tap a tag to the NFC reader, and the TeensyROM boots your game. No need to fumble with LOAD “*”,8,1. That’s not only cool, it’s convenient – especially for retro demo setups.

What truly sets this apart is the reintroduction of physical tokens. Each game lives on its own custom-designed card, styled after PC Engine HuCards or printed with holographic vinyl. It’s a tangible, collectible gimmick that echoes the golden days of floppies and cartridges – but with 2020s tech underneath. Watch it here.

Hackaday Links: February 12, 2023

So, maybe right now isn’t the best time to get into the high-altitude ballooning hobby? At least in the US, which with the downing of another — whatever? — over Alaska, seems to have taken a “Sidewinders first, threat identification later” approach to anything that floats by. The latest incident involved an aircraft of unknown type, described as “the size of a small car” — there’s that units problem again — that was operating over Prudhoe Bay off the northern coast of Alaska. The reason that was given for this one earning a Sidewinder was that it was operating much lower than the balloon from last week, only about 40,000 feet, which is well within the ceiling of commercial aviation. It was also over sea ice at the time of the shootdown, making the chance of bothering anyone besides a polar bear unlikely. We’re not taking any political position on this whole thing, but there certainly are engineering and technical aspects of these shootdowns that are pretty interesting, as well as the aforementioned potential for liability if your HAB goes astray. Nobody ever really benefits from having an international incident on their resume, after all.

Cardboard Game Tokens Become Shiny Click-Clacks With DIY Treatment

November 30, 2022 by Donald Papp 30 Comments

Tabletop games and cardboard tokens go hand-in-hand for a good reason: they are economical and effective. However, their tactile attributes leave a little to be desired. There’s something really great about high-quality pieces possessing a shiny, pleasing smoothness and click-clack handling that cardboard simply can’t deliver, but that all changes with [Dzhav]’s simple method for converting cardboard tokens into deluxe versions of themselves with a little work and a resin coating.

The result is a token with a crystal-clear, smooth, and slightly-convex coating of hardened resin on it. They feel (and sound) like plastic, rather than cardboard. The resin used is a two-part clear jewelry resin, used for casting things like pendants. It benefits from a long working time and unlike UV-cured resin (like the SLA 3D printer resin) it won’t be affected by light.
