Super Mario 64 was released in 1996 as a singleplayer video game. Recent mods have let two people play together, but a new romhack allows up to 24 to jump online and play through the game, kicking and punching each other all the way through.
SM64 Online is a project by Kaze Emanuar, Melonspeedruns and Marshivolt. Built atop a Super Mario 64 ROM, it lets people connect online, choose a character from the Mushroom Kingdom and play the game however they want. You can do traditional stuff like just clearing stages, you can have speedrun races or even just build a giant battle royale:
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
