Does not work on emulators, so please don't complain to me about that :) (but please DO complain about everything else, tho)

Legitimately, a technical breakthrough for the ST. Everything about this should be impossible, and the "standard" approach to this kind of effect would be very very far off running in a single frame at one pixel granularity, even in a window a fraction of this size. This therefore is pure genius/witchcraft - thanks for much Newline for pushing hardware innovations, even in 2024.

Great STuff, Tin!

Great achievement!

I've been exploring visualizing 'bus activity' technique this year:
what a coincidence ;) https://dhs.nu/bbs-scene/index.php?request=20284

I don't ever comment on pouet

But I do now. This is absolutely awesome! Great work tIn - this is hardcore hardware exploitation!

WTF, awesome

As if writing fullscreen code was not complicated enough, now all instructions need to use 2 words ! Congrats for such technical demo and thanks for breaking Hatari (in fact Hatari can support a very simple bus display mode, but it's very slow and must be enabled at compile time and in all cases it would not support this demo).

Now that there's a real use case of the "bus noise", emulation can be improved to match the expected result.

Once again : huge stuff !

Note that demo crashes with 4MB ; not sure it's due to Hatari but to the technique used, maybe the demo should refuse to start if STF has mor than 2MB ?

I only partially understand what was done here, but respect due!

I haven't even seen this yet, but the title compels me to thumb it up. Probably the best title I've seen this year.

And of course I forgot the thumb...
rulez added on the 2024-07-08 01:56:35 by Frost Frost
Very curious to see this in action. Hope a video shows up soon!
added on the 2024-07-08 03:13:05 by Jobbo Jobbo
@Mr. Styckx: that crash is a long known (at least to us) Hatari bug, it ofc works on real HW with 4MB:) I'll be giving some more details as to why Hatari crashes in my writup.

Everyone asking for a video: just watch the archived compo stream for now - https://m.twitch.tv/videos/2190856301 (plus some snarky remark to just watch it on real HW etcetc)

cool idea...

remembers me alot to the vc20 unconnected memory trick... if you set the screen to a memory location where no ram is installed...

the video chip displays all what is happening on the bus or better the last byte which was read...
really funny mode on vc20 since you can have some kind of packing of the screen data.
i descripe it here in more detail: https://www.pouet.net/topic.php?which=10628&page=1#c510790

anyway ... good job :)

it seems there is something very tricky here, please share some video ;)

Now that's one fancy rotator!

Impressive stuff tin! and thank you for making use of my old ika i rutan-skeleton dance cover that had been collecting dust since the mid 00s.
Because this tune finally saw some daylight, I tried to look up the real author.

Unlike the shows intro music, this piece lacks any mention or credits in the SVT archive. But since he composed the rest of the music for the show and have a track registered with STIM called "cirkusdans" that matches the length, I'd think its a fair guess that the original track was also composed by Lars Demian, but only Ika would know

Until someone makes a youtube rip, here is a working video on twich.

Great work guys, extra plus for the intro and the title :)

Thanks for the video, the rotation screen looks awesome!
rulez added on the 2024-07-08 11:59:18 by StingRay StingRay
I don't understand, but the rotation seems incredible! Well done!

Thanks. Looks great! Interested to read how it works.

great trick

i can't find the correct words for this

Wow. Very clever trick.

To me, this resonates like one of the most impressive technical achievement of all time on the Atari ST platform. Congrats tIn. I love the technical aspect of it and I love the execution. Pure awesomeness. The funny intro and the music fit in there very well too.

Mad new screen mode with neat presentation and music. What's not to adore here?

Could this have been entered in the zero bitplane compo?

hardcore technical stuff, I love it
rulez added on the 2024-07-09 15:18:20 by gwEm gwEm
just looked at youtube video, figured out it even runs in fullscreen, and STF.. I've no fucking idea how it works, and I love that! :) Congrats!

neat one

Oo i wonder how it's done
it's neat

No idea how it's done. Impressive stuff!

Impressive trick, impressive result. Best compofiller ever.

Quite some mad trickery in this one! Very clever! Love it!

Utterly brilliant. Anyone downvoting this doesn't understand demos.

Yet another frontier is broken. congrats!

Sourcery! Sauce erry! What is this dark magic!?

Lov the tech, mind blown, bricks shat. A real head scratch before - and after - I had the tech explained to me.

Warning, boring write-up, fresh from the press: Anatomy of a Compofylla

Pure magic

Thank you for the detailed write-up!

So cool that you're able to demo new (to the rest of us) tricks on the ST!

Also, I'd be curious to read how you managed to pull off the skew rotator on a plain old ST, especially with half the CPU limited to those moves.
added on the 2024-07-11 22:59:23 by Jobbo Jobbo
Just adding to the praise here, amazing new ST-tech almost 40 years into it's lifespan. Hats off to tIn.

evilpaul: No, this one's using bitplanes for display.
rulez added on the 2024-07-11 23:25:22 by evil evil
even better with the write-up, thanks a lot

Wow, I saw a pixel perfect smooth rotozoomer, then I realized it was even more than just a soft rendered effect. I don't even understand the hard technique here, I need to read more carefully the minisite link.

OK. A bit repetitive.
