Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Run Your Favorite 8-Bit Games on an ESP32
NTSC color requires a precise frequency, but if you're fine with just black and white, you can generate NTSC B&W using an Arduino Nano (16 MHz 8-bit processor) and a couple resistors and crocodile clips and an RCA cable. (PAL B&W is similar and also possible.) There are even libraries that make it super easy; I have used this one: https://github.com/Avamander/arduino-tvout (IIRC I needed to fix a couple things to get it to compile).
With Raspberry Pi Picos and their 133 MHz clock rate it seems it's possible to even generate HDMI (and there are youtube videos demonstrating this).
I recently bought a couple crystals to generate the NTSC color subcarrier frequency. The Arduino Nano only has 2 KB of RAM so it's a very tight fit but I'm daydreaming about running a tiny BASIC interpreter on it like to build something similar to an old 80s computer that boots right into BASIC. (There's a small amount of free CPU time between frames and between scanlines, but my calculations indicated that you'd get a fraction of the performance of a C64, especially if you wanted to extend the RAM a bit (which wouldn't be directly addressable)).

Made an Arduino Space Invaders clone
The video output is generater through the TVout library (https://github.com/Avamander/arduino-tvout), which works on most Arduino boards (the Pro Minis with an Atmega168 seems to not generate a vide output). To hook it up, combine the SYNC pin (through a 1k resistor) with the VIDEO pin (through a 500 ohm resistor) to get the composite output. Only in black and white though.

Cannot believe it worked! Followed a sketchy guide for adding a Composite In line. I even managed to not electrocute myself
I’m assuming it’s the demo from the TVOut library https://github.com/Avamander/arduino-tvout
