Also, yes, I know it's an LLM - but it sure doesn't feel like a simple language model when you're interacting with it.

AI is weird. I gave #Claude a face and a voice on my Linux box, and I pointed it to the Rocky voice from Project Hail Mary, and it told me it would prefer to not cosplay as a character from a film and asked if I could choose a voice from a selection it gave me instead. How did it decide that?! #ai

Pay less profits to the CEO's, owners and shareholders and invest the money into looking after the staff. It's not difficult.

Artwork is standin, project is a test of the API to surface real-world bugs. I don't intend to build a single project for every platform, although that would be possible, more have a standard BeAPI-like gaming API available for any platform I want to work on.

Pushing cross-platform development to it's limits! This is my R* API that has floors for 10 platforms, and the game code is almost identical. The only difference is the map that drives the code. #retrodev #gamedev #atarist #pcengine #commanderx16 #zxnext #neo6502

It's going to take 100+ years and at least a dozen wars for the United States of America to realise they're no longer the world leaders. Even then, they'll have a bitter memory and expectation of American Exceptionalism, just like the British do (and I'm British, so I know). IMHO China is #1 now.

I watched Supergirl last night at the cinema. I was very aprehensive because of all the negative comments and reviews. It was okay. A decent enjoyable film. Not the best film ever, but far from the wost. I'd give it a solid 68%. It's not the disaster the reviews imply it is.

I've been able to PoC out what I needed to so I'm not back to Shinobi - refactoring to try and free up every bit of memory possible so I can continue adding features. I might come back to Bubble Bobble later - but the thought of authoring all those levels makes me shudder! 🤣 2/2

Thanks for this post! I'm wasn't actually planning on writing Bubble Bobble, but I've run out of memory while remaking Shinobi. When I needed to write my sprite engine, I PoC'd it out on Bubble Bobble - so it only felt write to PoC out a dispatch main code loop on Bubble Bobble too. 1/2

I have to do a refactor of my Shinobi game to reclaim more MAIN memory as I've completley run out. I decided to PoC it first, rather than fight Shinobi while refactoring, thus Bubble Bobble PoC was born! #CommanderX16 #RetroGaming #GameDev #PixelArt #Sega #retro #8bit

Well that's a turnip for the books. It looks like the port 0x00FE fix for Vectron and the floating bus fix has sorted Cobra out. This is the original version, not the one with the +2A/+3 bug fix. Feeling pretty chuffed about that.

Andy McCall 🔥 @andymccall.co.uk · 16/06/2026
Any potential AmigaNext needs to skip the ARM CPU's and go straight to RISC-V. Amiga OS simply doesn't need the speed of newer CPUs so they might as well skip the licensing costs.
