The less good news is that it isn’t accurate enough yet, so player 1’s ship jumps around a bit This is because I’ve used Elite’s own dot product code, which was designed for visibility checks, so only the sign bit is accurate I’m writing a double-precision version that I hope will fix this (4/6)

The second speed-up is to replace the loop-based multiplication and division routines of the original with the log-based routines from the #C64 and 6502 co-pro versions. You can see the speed increase here: loop normal routines on left, log-based routines on right. (3/4)

The incomparable @negativecharge.bsky.social recently converted the Commodore 64 Elite music to the Electron. I've finally found time to add it to Electron Elite. Here's the docking computer in all its one-channel glory. Turn your sound on! #retrocomputing #retrogaming #electron #bbcmicro #8bit

I've managed to build the recently released source code for Elite II on the BBC Micro. It does... something! Though I have absolutely no idea what is going on. Still, here it is: Elite II from 1985. I think they're in trouble, whoever they are... #retrocomputing #retrogaming #8bit #elite #bbcmicro

Here’s an example - the iconic box art from the BBC Micro version, brought to life in-game. And there’s a Commodore 64 version too. You can even swap files between the two, so you can create a scene on a Beeb, save it and play it on a C64. I really enjoyed building this one, I have to say!

Player 1’s scanner view is in cyan, player 2’s scanner view is in yellow. Players will be able to choose different ships and loadouts The good news is that this proof-of-concept confirms that the geometry behind two-player Elite is sound That’s the tricky part, so this is a relief! (3/6)

Goodness gracious, great balls of fire! (In enhanced #Acorn #Electron #Elite, that is.) The speed isn't bad, considering the sun is probably the most screen-memory-intensive (i.e. slow) feature of #BBCMicro Elite. More clips in thread. (1/3) #retrocomputing #retrogaming #8bit

The first speed-up is to move speed-critical code into sideways RAM. Main memory on the Electron is shared with screen memory so it can only be accessed at 1MHz, but SRAM can be accessed at 2MHz, so this can really help. You can see the speed increase here: original on left, SRAM on right. (2/4)

This is pretty cool. It's a visualisation of the internals of The Sentinel on the #BBCMicro. This is it generating the game landscape for the first level from 256 pseudo-random numbers. Next week I'll be releasing a deep dive into exactly how this works. #retrocomputing #retrogaming #c64 #8bit

This is my first time using a memory heatmap to analyse #BBCMicro code Here's The Sentinel calculating landscape visibility (b-em emulator) Look: ray-casting radar patterns matching the landscape layout, right there in memory! The algorithm revealed! I love this #retrocomputing meta-level stuff 🤯

1/2 My debate last night: – The US–Israel attack directly benefits Russia and its war against Ukraine. Oil prices have surged enabling further financing of 🇷🇺's aggression. – The alliance between Donald Trump’s administration and 🇷🇺 is visible in their support for the neo-fascist AfD in Germany. 👇

PM Carney: "Being part of Canada brings many economic advantages, being part of our large market, being part of free trade agreements with 1.5B people around the world. But in the core, it's more than economic arguments, it's social, it's what we are as Canadians. Canadians take care of each other."

Bold climate action needs something powerful behind it: people who show up month after month. 🌍 That steady support fuels the work to challenge corporate polluters, pursue litigation, and move fast when real opportunities for change appear. #GreenSky

Trump and I both went to Wharton, but unlike him I went to class. Soaring costs are a direct result of Trump’s economically illiterate policies: tariffs, killing clean energy, and slashing Medicaid/ACA to fund billionaire tax breaks. Working families are paying the price.

While ordinary Americans choose between driving to work and food, King Donald the Mad's daughter and idiot son-in-law are developing their own private island. And bragging about it like no one should be offended. Still, the words "trump" & "private island" are synonymous with people getting fucked.
