Today's addition to #Acorn #Electron #Elite is the energy bomb animation from the Apple II, BBC Master and NES. In the original Electron version, the energy bomb did little more than beep gently. Now it rages with lightning bolts! That's much better. #retrogaming #retrocomputing #8bit #bbcmicro

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
Approaching the sun through a minor asteroid belt. I've always loved flying towards the sun in BBC Micro Elite, so it's good to see it on the Electron. That ball of flickering fire hanging in the blackness of space always has such a feeling of remoteness and grandeur. (2/3)
Overall the speed improvements aren’t too bad. They don’t quite reach the speed of the #BBCMicro shown here, as screen memory and zero page are still accessed at 1MHz, so there's a limit to what's possible. But hopefully it’s enough to support Thargoids, suns, planetary details and more! (4/4)
The enhanced version of #Acorn #Electron #Elite continues to grow. I've now added the ship hangar, which gets shown when you dock. This feature was only in the BBC and NES versions, and not the Commodore 64 or Apple II, so that's a one-up for the Elk. 🫡 #retrogaming #retrocomputing #8bit
My new project is a version of BBC Master Elite, but with a twist. Sure, it’s pretty niche, but this has never been done before, which is always fun. Can you tell what it is yet? The clue's in the clip... #retrocomputing #retrogaming #bbcmicro #8bit #elite
I've also implemented fuel scooping, so those fuel scoops can finally be used for... well, scooping fuel, and not just cargo canisters. Don't leave home without them! (3/3)
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 🤯
Enhanced #Elite on the #Acorn #Electron now has 31 different ship types (compared to just 11 in the original). Here's a little clip showing an encounter with a Krait and a Mamba on the way to the sun. Coming soon... Thargoids! #retrogaming #retrocomputing #bbcmicro #8bit
Not sure if this animated GIF will look any good on here, but the latest batch of articles talks about how the 3D objects are drawn, such as the Sentinel example here. It's pretty interesting when it's slowed down...
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)

Kristi Noem has been fired. Good riddance. But the problems at DHS go much deeper than any one person. The President must rein in ICE and end the violence.
