To explain further:

The B+ is a Model B with an extra 32K of RAM, split into 20K of shadow RAM and 12K of very bizarre and hard-to-use "private RAM". But it turns out this is just enough to contain the BBC Master version of Elite, with all its colours and extra ships and whatnot.

So I just had to!

We have a winner!

This is the BBC Master version of Elite backported to work on the unexpanded BBC Micro B+. The B+ was almost totally ignored back in the day and was swiftly replaced by the Master, so for the B+ to have its own enhanced version of Elite is a pretty big deal. For B+ fans, anyway. πŸ™‚

Elite Compendium - Elite on the 6502 Details of the Elite Compendium, which brings all the best Elite hacks together in one feature-packed disc

Already (kind of) did that with the Elite Compendium. πŸ˜€

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...

Gosh, it runs C64 software! I hadn't realised. That's pretty interesting.

Two ways. Either temporarily move the problem code into main memory for debugging and move it back when I’d fixed it, or switch to Elkulator as a last resort (the monitor in Elkulator is really primitive but at least it works with SRAM).

Really looking forward to SRAM support in your debugger!

Well, I did have a rather excellent development environment! I’m a big fan of your VSCode/max65/Electroniq setup, it’s great. πŸ˜€

Exactly. And the Cougar. I mean, it has a cloaking device! Sounds like it would be fun in E:D.

Yeah, Elkulator crashed when I tried to save the screenshots for my site. Had to grab the whole screen when it was running instead. Still, worked OK in the end. πŸ˜€

Anyway, really glad the game itself is working! That’s the important part. πŸš€

Elkulator and Clock signal both have sideways RAM, though neither of them mention that fact. Both work well with the Compendium version. And Electroniq in the browser does too. Not sure which OS you’re on, but these have pretty good coverage?

Thank you! I clearly like to type. πŸ˜€

Rock hermits are asteroids that dispatch defence ships when you attack them. And the Cougar is a ship with a clocking device, so it’s hidden from the scanner. Nice features, but for the advanced versions of Elite only…

Hope it goes well. πŸ˜€

I’m sure there will be some pesky bugs in there as it’s been a pretty complicated project, but hopefully it’ll hit the spot. Let me know if you do spot any issues and I’ll do my best to fix them!

Clean the house. Do the gardening. Sleep. Drink a cold beer under the parasol.

And dream of Thargoids silhouetted against the glimmering sun...

It's done! I have just released the Compendium version of #Elite for the #Acorn #Electron.

This massively enhanced version of the original game contains pretty much every feature of #BBCMicro Elite, but on the Electron. Just add 16K of sideways RAM.

Links in thread.

Yes. Electron Elite is essentially BBC Micro Elite with features removed and slightly different graphics and sound routines, so data like the text tokenisation system and ship blueprints are identical.

A sense of scale - Elite on the 6502 A deep dive into scale in Elite on the 6502

Well, it’s a bit of a cheat. I calculated that the humble Cobra Mk III can house an energy bomb for just 900 credits that’s capable of destroying an entire planet and pretty much everything in low-to-medium orbit around it. Ouch!

See elite.bbcelite.com/deep_dives/a... for more nonsense like this. πŸ˜€

Thank you! I’ve found a few bugs that I need to fix first, but hopefully this will be ready towards the end of this week for everyone to try. Fingers crossed… πŸš€

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.

Playing 6502 Elite in the 21st century - Elite on the 6502 How to play all the versions of Elite analysed on this site

I don't know much about the non-6502 versions of Elite, but for the 6502 versions, the Commodore 64 and NES versions have all three missions.

Then again, so does the Elite Compendium, which is my recommended way to play the game these days:

The Compendium version of #Acorn #Electron #Elite now has missions - three of them, in fact.

Here's the briefing for the Constrictor mission, backported from the #BBCMicro; I've also ported the Thargoid plans mission, and the Trumbles from the #C64 and #NES. 🫑

I still can’t believe it was 41 years ago! Time flies. 😳

I really regret selling my Archimedes A410/1 (luckily I held on to my Beeb). I loved that machine so much. I’ve since picked one up secondhand, but I still regret selling my original. I guess everyone has a retro-related regret somewhere…

The Compendium version works out-of-the-box on the emulators that I’ve tried: Elkulator and Electroniq.

Elkulator is for Windows and Linux. It even emulates joysticks, so you can use a game controller if you want.

Electroniq runs in a web browser, so it works pretty much everywhere. It’s great!

It’s taken about 5 weeks of spare-time coding to produce both the Econet version and the Compendium version of Electron Elite (they’re forks of the same sideways RAM game core).

It’s been a busy summer!
