More work on my #RetroChallenge today. I was taking the out from the NES controller, reassembling it on the #RC2014, and showing the output in the red LEDs. I then noticed that I’ve accidentally reassembled the byte backwards. Oppps

I tried to emulate 90's Anime, I don't think i succeeded, but it still looks DREAMY. #90's #anime #retro #art #digitalart #unicorn #cute #challenge #retrochallenge #comic Upsilon looks just as good in 2d as he does in 3D!

I'm not able to take part in #RetroChallenge this year, but I've just spent a few minutes enjoying last year's writeup of my #Sharp #MZ80K emulator for the #RaspberryPiPico . The plan for winter is to have a bash at #MZ700 emulation - faster clock & colour too!

There was a native gui editor for 42nix (my team did use it, but preferred vi as it was standard across UNIX workstations). The little-known ded text editor was also available. See my abandoned 2023 retrochallenge for details and a link to the MG-1 manual entry. z80.timholyoake.uk/retrochallen...

It's the final day of the #RetroChallenge so I've written about my finished project.
In this post I explain how I was able to connect my RC2014 NES Controller module to a Sinclair ZX Spectrum, and how I hacked the Manic Miner code so I could use my new module.
