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)

I am working on speeding up #Elite on the #Acorn #Electron. It's going well. On the left is the original; on the right is my enhanced version. It's all down to sideways RAM and backporting faster code from the #BBCMicro and #C64 versions. More details in thread. (1/4) #retrocomputing #retrogaming
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)
Two-player #BBCMicro #Elite is coming along nicely. It now supports two pilots in two ships with two controllers and a split-view screen Here are some work-in-progress videos - see the thread for an explanation There’s lots to fix, but at least we have a proof-of-concept… (1/6) #retrocomputing
The videos show player 1 (top) in a Cobra Mk III and player 2 (bottom) in a Viper They demonstrate both ships independently flying past each other This clip shows the rear view working too Though it’s a bit hard to demo a two-player game when there’s only one of me! 😂 No lasers yet… (2/6)
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
Bonus video: someone asked me to show the two ships looking at each other in a spaghetti-western style. Here you go: Cobra vs Viper, head-on. It doesn't end well.
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!
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
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)
This graduation season, schools across the U.S. have continued their attempts to silence pro-Palestine speech. Rutgers professor Noura Erakat says repression of Palestine protest only spreads outwards. "We are the Trojan horse to bring in these policies that will affect everyone."
