\o/ Yay! Thanks for organising this venue again. It was a great weekend last time and so conveniently close for me at least. Look forward to the booking thread.

Great progress Tricky!

Like Mark, I have a stack of gardening jobs to do over the coming weeks before starting my new job in September. However I would love to borrow a rifle at ABUG please if anyone would be kind enough to lend one for a while.

Just FYI that although POP and SCR do blatantly abuse the 12K of HAZEL (FS) RAM they do try and step around the areas that are known to be used in a standard Master DFS/MMFS setup that leaves PAGE at &E00.

I think SCR even works on ADFS thanks to Tom Seddon!

Hey 0xC0DE, I'm surprised Twisted Brain loads (!) but in general having PAGE at &1900 on a Master is going to cause problems with more advanced software like Stunt Car Racer (and Prince of Persia) that requires PAGE at &E00 and all 4x available slots of SWRAM (plus ANDY and a chunk of HAZEL for good...

Can you post a screenshot? My bad but TB kinda assumes a fresh boot in either MODE 7 or one of the 20K screen modes. Too much testing on an emulator rather than real hw! If you have the VLSI variant 6845 CRTC chip then it is known not to behave ‘correctly’ compared to the other manufacturers, eg Hit...

Welcome to the forum Vincent - San Diego is a long way from home!

I have to confess Elminster's avatar reminds me of my old Nest thermostat, although I'm sure that's not the intention.

OK, OK, I know I’ve been on a bit of a binge recently but I do need a backup Master and couldn’t resist the sweet cherry keyboard...

Last one for a while, I promise!!

OMG! If you make a lightgun for the Beeb I will write a game for it for sure.

(Although some kind soul will have to make me a lightgun to test it on.)

Does this SEGA gun work like a NES Zapper or like a more ‘modern’ lightgun?

Alas, people, Viper21 was a reincarnation of a user who was previously banned for trolling. Suffice to say this was another one of his lo-fi attempts and he's been banned again. That’s a shame (the trolling, not the banning) because it’s a genuinely interesting question and I do consider MODE 0 to ...

Yes some fast RAM is essential for WHDload. Don't even bother trying to load WB 3.1.4 without some fast RAM. Get a CF to PCMCIA adapter because you can install fat95 & CFD and mount a fat32 formatted CF card as a hard disk - I bought the cheapest from eBay and it works just fine. If you get fast RA...

Making lovely hi-res copper colours on a Beeb?

viewtopic.php?f=53&t=15300#p207230

That's a lovely looking A1200. I bet that cost you a pretty penny. Does it come with any extra bits and bobs? Thanks, I’d say it was a fair market price, not a bargain but not a rip off. It is a lovely light shade although the accompanying tank mouse has a proper mahogany tan. :lol: It’s got a coup...

I couldn’t resist treating myself to something non-6502 based after finally securing a new job!

Welcome to the forum Simon! Whereabouts in Hampshire are you? There are a few of us not too far away in Surrey and ABUG South has previously taken place in Camberley.

Cheers,
Kieran

Welcome to the forum fellow Hullensian! Although you would never know I hailed from there anymore now my accent has been rounded to a more ‘generic northern’ after years living in the south and working in London. :) Lovely collection of Acornsoft tapes you’ve got there! Keep up the good work, gotta ...

Another 6502-based machine to add to the collection. It’s still got the plastic on the Atari nameplate. So tempting...

Nice! I love my Vectrex. Glad I picked it up when I did because they are not getting cheaper, that’s for sure. I fancy doing some home brew for it one day (add to the backlog) because of the crazy 6809 chip, sweet vector display and deep bassy sound. Edit: PS. I might bring mine to ABUG at CCH for a...

Could have done with an Elk version back in the day, had to suffer playing it on a mate's ZX ! :( Just tried the BBC cheat version (the original version didn't load) from StoH, and it kind of works - the screen is off-set wrong, so it wraps around ! Might be fixable with a look at the code............

I’m surprised there isn’t an Elk version already TBH as there’s no technical reason why not, particularly if it ran in MODE 4 rather than MODE 1, which was the usual approach to porting. Has Kees made an Atom version already? That would probably be the most sensible place to start, rather than from ...

I was unreasonably hoping "a null modem cable"

A bit optimistic. Sadly head-to-head play wasn’t added until the 16-bit version of the game so you’re limited to turn-based multiplayer I’m afraid.

Completely spit-balling here, but could you do a TAPE MMC instead of a disc one to keep the RAM overhead low? So the sd card just has tape images on it that you can select with some sort of *TIN command then everything else is just data streamed through the existing tape code, just with bytes coming...

\o/ Yay, Acorn World! Thanks for organising again Jason. Please can you put me down for a full table for all three days. Might as well bring my Master for POP and SCR action.

Thank you so much! You're absolutely right, I changed my variables to the first page (i.e. &0170 for NUM1, &0171 for NUM2 etc.) and the programs assembled with one less byte in the rewritten program, as the BCC command only requires a single byte to increment the program counter for the branch. Als...

If you want a real workout of your 6845 emulation then try Wave Runner or Twisted Brain from here: https://bitshifters.github.io/

Note that they are Master only and Wave Runner also uses 1-cycle NOPs...

Hey Kees, great to hear that you've made some new progress with the BBC port of AGD. Sorry I wasn't able to take it further than I did but my heart wasn't quite in it compared to the lure of Stunt Car Racer. :) I'm happy to help with any questions about BBC technical specifics and approaches, like t...

In a most unlikely turn of events, the NOVA demoparty shader showdown was featured in an article in the Sports section of the i newspaper today...! (EDIT: the unlikely turn of events mostly thanks to our own sbadger :D) IMG_20190624_093638.jpg You can read the article online, this time with BBC grap...

OMG, yes! I should have also added that Stardot’s very own Sarah Walker has made the first new Archimedes demo in probably 10 years... and pretty awesome it is too!!

I must've joined around the same time, excellent demos, but no idea what I missed beforehand. Could be tempted to attend sometime, maybe next year. The website says there's someone there that recaps Amigas, is that a regular attendee, my original A1200 has not been powered for many years so is prob...

For anyone that's interested in what a demoparty is like, there's a live stream of the NOVA event taking place right now: https://www.youtube.com/watch?v=tSrzg1MnYtc Our very own VectorEyes and Tom Seddon have taken up the Bitshifters mantle this year, so we'll see what they come up with for the Old...

No. Again it was on the list, particularly when I originally planned MODE 1 so just four colours, but after Dethmunk provided such wonderful eight colour MODE 2 graphics there didn’t seem to be much point in revisiting. Technically the sprite engine permits three independent colours per sprite from ...
