Later in the episode @davevelociraptor.bsky.social mentions “sometimes you can get Infocom games which you can bolt on an auto-mapper to a lesser or greater success.”
What are these 'auto-mappers'? I have no familiarity with this 😯
When I were a boy I wanted to code a #BBCMicro map creation tool 🤓

I've started writing a series of deep dives into Geoff Crammond's epic #BBCMicro game The Sentinel.
Here's the to-do list.
I will post a link here whenever I add a new one to thesentinel.bbcelite.com
It's going to take a while! But it should be worth it...

If you think a #BBC #online #space is fanciful, think of what BBC technology has brought us inc: Marconi microphones, loudspeakers, stereo #TV and #computers like #BBCMicro and micro:bit; #@BBCiPlayer its video on demand service, launched on Xmas Day 2007. Change through #publicservice innovation.

Here's a quick SN76489 interface I cobbled together for the SAM Coupe along with coding a simple .vgm player to play music from the BBC micro. (Here playing a rendition of Supremacy converted from C64 to SN by Negative Charge)

Sobering reflection from Robert Albury and David Allen - directors of the BBC Continuing Education department - reflecting on the rise of microprocessors in 1979, in language that could so easily refer to the current AI boom:

You didn't know you needed this in your life, but you do.
Marine Beaufils is a French artist who creates beautiful embroideries of... The Sentinel (amongst others).
It's inspired and quite beautiful. Enjoy!

Have you ever wondered how big the full landscape is in The Sentinel?
It's 1856 pixels high and 2048 pixels wide.
Here's the first level. The initial 192x160 screen is in red. Panning jumps the view to different grid points.
It's a big old world!

I have documented the #BBCMicro version of the game to start with, and I hope to add the #Commodore64 version later.
On both platforms The Sentinel is a stone-cold classic.
It boasts filled 3D graphics, eerie silences, utterly unique gameplay and an atmosphere you can cut with a knife.

Another attempt at a BBC Micro Mode 7 demo effect today - the Moiré pattern. Could do with some colour and further optimization, but just wanted to get the basic effect working. This demo is accompanied by some classic Mad Max {Jochen Hippel) music. 🔊

More 6845 CRTC experimentation on the BBC Micro. This time it's Mode 1 and an infinite vertical scroller. I'm probably not doing this right as it's not as smooth as I would expect. Need to do some more reading on this one. No music with this demo.
