And again, good job with this port. It's a funny little game, that I'd also never heard of, but quite addictive once you get into it, as you say. I love the NULA version in dreary grey, very authentic! I think I like your MODE 1 colour choices better. Enjoyed the video again too.

So many games! You have been busy Tricky. Great work once again, and also enjoyed the video a lot hearing about your history with the game and the details of how it works. Good stuff.

Excellent work Tricky, as ever! And a fantastic video, really interesting to hear about the details of making the game.

Now, about that 6502 copro version with line drawing in MODE 0.

I'm looking forward to catching up with some of the presentations I missed. The ones I saw were very inspiring and it's great to see people still developing for the Atom, Beeb, Electron and Archimedes. Kieran, your 'introduction to timer interrupts' was superb! I remember trying to work out this st...

Nice to see everyone last night and thanks again to Arcadian for organising. I hope the Intro to Interrupts session was practical and useful. All the text and asm code can be found on GitHub: https://github.com/kieranhj/intro-to-interrupts. In the spirit of improvement, please feel free to PM me wit...

Oooh, if Chris is presenting please put me down for the afternoon & evening.

(The README contains full acknowledgements of those whose shoulders I have stood on for this project, but I must give a particular shout out to kieranhj, whose original port of the source code to BeebAsm gave me the starting point for this project. You really inspired me, Kieran - thank you.) This ...

Looking good! Nice to see so many wolves on screen at once, really gives it that arcade feel.

Looks great!

Is this running on a Pi copro streaming over the Tube? I’ve tried some simple delta video codecs streaming from floppy in MODEs 4 & 7 with mixed results. I’m thinking Smacker is likely going to be too heavyweight at 4kb/s + 2MHz 6502?

Love the MODE 1 ‘hires’ look - I think dithered ghosts would work well too. EDIT: I see what you mean about the challenge of having a 288 pixel high screen. I think having lives and fruit on the side looks fine but the scores feel a bit cramped. Any chance you could leave them at the top? What heigh...

Thanks Dave, thanks BigEd. By a fortunate coincidence, TobyLobster just started a thread about their BBC MOS Reassembly: https://stardot.org.uk/forums/viewtopic.php?f=54&t=20303 This looks like a great resource - you can step through the MOS IRQ handler line-by-line with comments here: https://tobyl...

I've been figuring out my calendar for this week, but have confirmed I can attend so please put me down for the full session! Project-wise I can do a show & tell of the Rocket Sync Tracker connected to Arculator - an interesting way of sequencing demos that has a lot of potential and may encourage f...

I don’t have anything as small as Hello World but there is a repo with a (slow) MODE 9 implementation of the Doom fire effect: https://github.com/kieranhj/doom-fire How basic a Hello World were you looking for? This is plotting direct to the screen in MODE 9, with a single buffers, although the code...

Hey, always great to hear when people are interested in developing for Archimedes! I posted this thread about my 'modern' development environment setup on Windows: https://stardot.org.uk/forums/viewtopic.php?f=29&t=18635. I'm not creating ADF or AIF files, just absolute executables, so assembled at ...

Now you mention it, I do have a very crusty issue 4 Beeb that has incredibly stiff & sticky keys that are quite unpleasant to type on and often don't connect even though they have to be quite deliberately pressed. I don't have a good answer to how to improve this, as I don't use it as my 'regular' m...

It's not a 'cherry' Master is it? The keyboard for those later models feels very different from a classic BBC.

EDIT: Pictures would help!

These are fabulous suggestions Kieran and it would be great if one of the aims of these Dev Nights were to be the creation of a video-based encyclopedia for would-be Acorn games/demo programmers, of all abilities. I think it would be beneficial if we could try and identify a 'programme' of topics t...

By good fortune I am free tomorrow evening so will join for the full session. I look forward to seeing everyone online again. :) I PM'd this to Arcadian, but on reflection warrants posting here for potential discussion tomorrow. I think it will be really important to establish the purpose & structur...

It couldn’t be in BASIC but on a Master you could do this at 50Hz with single pixel horizontal & vertical movement in MODE 2 by using vertical rupture to scroll vertically one scanline at a time, plus SHADOW RAM to offset a second copy of the ball by one pixel. For the background you could make a fi...

If you want to write the debugger Steve, I know we’d all be grateful!!

Thanks again to all the organisers! Please put me down for the day. Looking forward to finding out what the sessions will be.

Nice! Although I'm never fan of flickering colours at 50Hz. I'm wondering though, would it perhaps be possible to make an effect similar to the 2-colour plasma from Twisted Brain?

Thanks. That would still be really useful actually as you’d end up with a PNG just containing the correct 256 colours for MODE 13. It would be easy to extend the above Python script to output the correct byte encoding for loading directly into MODE 13 screen buffer. I don’t really want to be reinven...

Yeah the library is a bit busted. That’s been filed as a bug, along with some others, on GitHub: https://github.com/shawty/BBCB_DFS_Catalog/issues/3

I’ve got a png2arc Python script but it only works for MODE 9 and requires input PNG images with <= 16 colours. It does spit out a separate 64 byte file with the colour palette values at least. https://github.com/kieranhj/stniccc-archie/blob/master/bin/png2arc.py It’s been on my list to do a MODE 13...

Coming from the Beeb I always forget the Archie has a border. I will borrow this idea for raster timing!

Welcome to the forum Tor! Any new Archimedes demos in the offing maybe? There’s been a small resurgence of late...

I’d like to attend this session please! I should be around for the afternoon and evening. Thanks again for organising.

The thought of trying to build a massive program like POP on a real BBC Micro brings me out in a sweat.

Well it seems like I can hardly let the POP fans down now, can I? This is a Release Candidate for version 1.2 that hopefully works with MOS 3.5 and Master Compact. I hesitate to call it a fix, more a massive hack :? so any testing on real hardware would be gratefully received before I update the off...
