Just enabled the Live Demo, check it out https://plrang.github.io/CHIP8-Interpreter-Vanilla-Javascript/ #chip8 #js #javascript #emulator #interpreter #spaceinvaders #retrogames #codingisfun #vanillaJS

Finally added the source code to Github: "CHIP8 emulator / interpreter in Vanilla JS" https://plrang.com/chip-8-emulator-in-javascript-that-runs-in-the-browser/ #chip8 #js #javascript #emulator #interpreter #spaceinvaders #retrogames #codingisfun #vanillaJS

It's alive! My CHIP-8 interpreter passes all the tests in this test cart: https://github.com/corax89/chip8-test-rom

Next up for today is playing some games, but tomorrow I'll see about adding SUPER-CHIP support.

@petterij Oli se huikeaa aikanaan kun sai 2 kilotavun muistinlaajennuksen ja koneen muisti tuplaantui neljään kilotavuun.

Ohjelmia oli aika paljon, yksi hieno oli hirviölabyrintti, josta näköjään löytyy videotakin.

Not sure why, but I am intrigued by #Chip8 and related projects, such as https://internet-janitor.itch.io/octo, and a ton of other links: https://github.com/Chromatophore/HP48-Superchip

Not sure what I wanna do with this... make my own emulator that runs in #makecode?

What to do in a hot summer day? Coding an emulator of a computer from the 70s for computers from the 80s, of course!

I know, I suck at games, especially lunar lander...
